Re: Apache James 3.0.0
That's a great news. Kudos to the entire team and thanks a lot for your efforts. I hope this is the stable version. We were planning to upgrade James 2.3.2 to 3.0 RC1. Now I can go ahead with this release.

Re: Tentative Date for James 3.0 GA
Thanks Matthieu. I got it..We have started evaluating 3.0 RC1. Will come back if I have any questions.. Thanks Mahesh On 24-May-2017 3:57 PM, "Matthieu EXT_BAECHLER" wrote: Hi Mahesh, We'll release "when it's ready". It's a non-answer to your question, I apologize. ETAs are usually something harmful because people expect Quality, Features and fixed release date, the truth is you have to pick two. I started to talk about switching from Quality+Features to Quality+Date aka time-based release. Not sure the community will agree but I don't want the next version to wait for 10 years. About SMTP : we use it on a small scale deployment and we have load-testing to exercise it, so yes, it's pretty stable I think.

Tentative Date for James 3.0 GA
Hi, Can someone please let me know the tentative date for James 3.0 GA ? We have to upgrade our current 2.3.2 in production to 3.0 as 2.3.2 doesn't support STARTTLS. Team is not recommending to deploy non GA version to production. Btw, is the SMTP component of James 3.0 RC stable ? Because our use cases need only SMTP. Thanks Mahesh

Re: AW: URGENT HELP: Backport STARTTLS from 3.0 to 2.3.2
Thank a lot Bernd...I will look at the handlers. The current requirement is
to act as a receiver.. One more question. I see James 3 SMTP implementation
is mentioned as stable. Is this true for STARTTLS as well ?

URGENT HELP: Backport STARTTLS from 3.0 to 2.3.2
Hi All, Did someone backport *STARTTLS* feature from 3.0 beta to 2.3.2 ? We have 2.3.2 running in production and there is a requirement to support STARTTLS. Since 3.0 is in beta, the team is not comfortable in putting into production. If the porting is not done, can someone please guide on how to implement this in 2.3.2 ? I can give it a try. Thanks Mahesh

Re: PRODUCTION ISSUE: James 2.3.2 Refusing connections..Need URGENT HELP !!!!!
Ours is a virtual machine (VMWare).. Max heap is set to 4GB.. I will do a stress test. Infact we did it during our LT (Load testing)... I will post the details here once I have enough data.. What I was trying to understand is "is there any possibility of the 30 max connections to go stale and not sent back to the pool".. If its an issue with the high timeout value, we should see the emails getting processed after 5 minutes... What is the ideal value for SMTP idle nowadays... I followed the default value in the config.xml Thanks for the help and pointers so far..

Thanks Özgür... This email application is not exposed to any real users with Inbox. Its an internal email processing application which will recieve emails routed from our Enterprise Email server.

Re: PRODUCTION ISSUE: James 2.3.2 Refusing connections..Need URGENT HELP !!!!!
Hi, Thanks for the inputs. We don't have any DB configurations. Its all file based. There are two servers which are already behind the load balancer. We were getting Too Many Open files issues.. We have increased the ulimit to the maximum two days back. Did you mean "decrease the timeout and increase the max-connections ?" In a 4CPU machine, can I increase the max-connections to say 100 if we came to know that its about load ?

PRODUCTION ISSUE: James 2.3.2 Refusing connections..Need URGENT HELP !!!!!
Hi All, We have rolled out James 2.3.2 to production for our email processing application. I see that James is no longed accepting connetions after few days of run. It processes around 100K email a day and sends a good amount of Notification emails through RemoveDelivery. James is running on a 4 CPU machine with 8GB RAM. Heapsize of James is set to 4GB with Openjdk 1.7. INITIALLY WE THOUGHT the server was getting killed/terminated. As per the latest information, server is not killed.. Our support team used to restart the server when we get "Connection Refused" error from port 25..We have a monitoring tool which Connects to James server every few seconds, and issue a QUIT command... This monitoring tool is getting Connection Refused error. Hence the team thought the server is down and followed the routine Stop, Start commands... I have the following configurations in various places in the config.xml. I have INFO logging enabled. I couldnt find any WARN messages about connections. SMTP Server (the only process enabled): 36 Spool Manager: 10 Connections Manager 30 30 Thread Manager default 5 false 100 20 20 The total number of threads (spool+remotedelivery etc ) are under very much under 100. We don't have any DB configuration in config.xml as well. Do you think the timeout values might cause the connection refused errors ?. Especially the idle-timeout ? Isn't 5 minutes too high ? If say 30 clients are taking few minutes, this will be more than enough to raise an alert from the monitoring tool...even if all the connections are being used, it should be release after the processing done right ? Is there any chance of the connections not being released and going back to the pool ? Please provide your comments.. Thanks Mahesh

Thanks Bernd. Enjoy your holidays and please help whenever you get time... :) Did you get a chance to take a look at my latest email ? Actually the server is not dead. Its refusing connections..

Re: URGENT HELP: James 2.3.2 not responding after few days of run
Hi Bernd, Here is some more information. As per the latest information, server is not killed.. Our support team used to restart the server when we get "Connection Refused" error from port 25..We have a monitoring tool which Connects to James erver every minute, and issue a QUIT command... This monitoring tool is getting Connection Refused error. Hence the team thought the server is down and followed the routine Stop, Start commands... I have the following configurations in various places in the config.xml. SMTP Server (the only process enabled): 36 Spool Manager: 10 Connections Manager 30 30 Thread Manager default 5 false 100 20 20 The total number of threads (spool+remotedelivery etc ) are under very much under 100. We don't have any DB configuration in config.xml as well. Do you think the timeout values might cause the connection refused errors ?. Especially the idle-timeout ? Isn't 5 minutes too high ? If say 30 clients are taking few minutes, this will be more than enough to raise an alert from the monitoring tool...

Re: URGENT HELP: James 2.3.2 not responding after few days of run
Hi Bernd, Our Sys Admin has NOT performed the following things while configuring james as a service. 1. Adding the below lines in phoenix.sh #chkconfig: 2345 80 05#description: James Mail Server 2. Chkconfig command chkconfig --add james They created only the link in /etc/init.d pointing to phoenix.sh. We can start and stop the service using the service command. Do you think not doing the above two steps will impact a running James in any manner ? I am trying to understand he run levels as well.

If there is a clean shutdown through RemoteManager, it should be shown in the log rite ? The thing is, I don't see any entry in the console log which says STOPPED..I am investigating and will keep you posted. Thanks for the help so far.

Re: URGENT HELP: James 2.3.2 not responding after few days of run
Thanks again Bernd... I couldn't find the hserr files under the temp or james directories. Considering we faced Too Many open files issue, will it prevent the JVM from not creating this file ? I am clueless on this issue. No process Killed James, Noone stopped James.. No OOM in logs.. No core dump :) :( Regarding the file system I will verify. As far as I know we have a NAS...

Re: URGENT HELP: James 2.3.2 not responding after few days of run
Hi Bernd, Thanks for the pointers. Let me ask the Sys admin on these details. Btw, will this memory leak be shown in the logs? I couldn't find any OOM errors in any of the logs. When the issue, happened, our team restarted the server. It will create a new PID rite ? Is there a way we can see the old pids from the james logs ?

URGENT HELP: James 2.3.2 not responding after few days of run
Hi, I need an urgent help. We have rolled out James 2.3.2 to production for our email processing application. I see that James getting shutdown (no trace in the phoenix.console) after few days of run. It processes around 100K email a day and sends a good amount of Notification through RemoveDelivery. I have verified the logs but I couldn't find any reason for this abnormal shutdown. I have seen couple of "Too Many Open Files" errors in smtpserver log and spoolmanager log. But I think those will not bring down the server. Will they ? I am not sure if James is killed by some other Linux process. James is running under a user (eg: james) account with sudo access to run on port 25. Since I don't have root access, what all areas that I look to figure out what the problem is ? If I want to talk to Sys Admin, what all information that I should ask him/her to gather ? James is running on a 4 CPU machine with 8GB RAM. Heapsize of James is set to 4GB. I have configured to run James as service in Linux. I am not sure if our Sys Admin run the chkconfig command. Is there any impact of not running this command ? Please provide your inputs as early as possible.. Thanks Mahesh

Could this cause any file descriptor leak ? 19/03/15 20:13:56 ERROR smtpserver: Socket to -xxx--xxx-xx.com () closed remotely. java.net.SocketException: Connection reset at java.net.SocketInputStream.read(SocketInputStream.java:196) at java.net.SocketInputStream.read(SocketInputStream.java:122) at java.io.BufferedInputStream.fill(BufferedInputStream.java:235) at java.io.BufferedInputStream.read(BufferedInputStream.java:254) at org.apache.james.util.CRLFTerminatedReader.read(CRLFTerminatedReader.java:153) at org.apache.james.util.CRLFTerminatedReader.readLine(CRLFTerminatedReader.java:113) at org.apache.james.smtpserver.SMTPHandler.readCommandLine(SMTPHandler.java:751) at org.apache.james.smtpserver.SMTPHandler.handleConnection(SMTPHandler.java:372) at org.apache.james.util.connection.ServerConnection$ClientConnectionRunner.run(ServerConnection.java:432) at org.apache.excalibur.thread.impl.ExecutableRunnable.execute(ExecutableRunnable.java:55) at org.apache.excalibur.thread.impl.WorkerThread.run(WorkerThread.java:116) Thanks Mahesh On Sun, Mar 15, 2015 at 8:33 PM, Mahesh Sivarama Pillai wrote: > Thanks Michael..

Need Help: LoadRunner with James 2.3.2
Hi, I have encountered an issue during our Load Testing with James 2.3.2. The load test tool being used is Load Runner. We have a corporate mail gateway to relay messages to internal mail servers. But we are not supposed to use it for Load Testing. So we have to send the email directly to the James server from Load Runner. Our Observation - When we send email through gateway from Load Runner, the email is received at our Internal Email server (James 2.3.2) without any issues - When we send the email directly to our internal James server, there are SMTP errors thrown like Syntax Error in MAIL command etc. - When I put the from address between "<" and ">" in LoadRunner script, "Syntax Error in MAIL command" got resolved. - Then I started getting some Message boundary exceptions. - When I use a Java Mail client and directly send the email to our internal server, there are no issues. - What I am thinking is (I may be wrong) “the email sent from the Load Runner may not be conforming to the SMTP standards. Our gateway is tolerant to these non-standard clients and might be formatting the SMTP message as per the standard” Is this understanding correct ? Please provide your inputs on this behavior. Have you ever come across this kind of scenarios and how it was resolved ? Any input would be highly appreciated. Thanks Mahesh

Notification on email processing
Hi, In my email application, I have a requirement to send out the notification to the sender or a pre-defined email ids about the outcome (success/failure) of the email processing. If I use mailetContext.sendMail, the mails will go to the spool and will take the standard processor flow and get into remotedelivery to send out the communications. The delay caused in this approach will depend on the number of emails in the spool for regular processing...When I say "regular processing", I meant the business logic of my email application built in the form of mailets. My questions is, Is this the right approach ? How about I use JavaMail api to send out this communications without bombarding the RemoteDelivery with the notification emails ? Please note that I don't have any requirement for relaying emails.. All emails sent to my JAMES installation will end after performing some business logic(including calling some web service rest/soap apis). The only outgoing emails will be the notification of the outcome... Any suggestions ? What is the best practice followed by the community in a similar scenario ? I have more questions. But I will start with this one.. Thanks Mahesh

JAMES based Applications/Products
Hi Guys, I have been searching in the internet as well as the James pages to make a list of products that are based on Apache James. Here is what I have got so far other than what is listed in the Wiki. Can you please add more to the list ? 1. Oracle Health Sciences Information Gateway (OHIG) Secure Health Email based on JAMES 2. Ascertia Secure Email Server based on JAMES Ideally these should've been part of http://wiki.apache.org/james/JamesUsers. Any plan for updating this list ? Thanks Mahesh
Re: Ignore email after processing
Those were really great tips Bernd. Yes I will have proper logging to analyze what happened to the email. In my case, the Corporate Exchange server does most of the stuff. Like virus scan/spam filtering etc. After that, emails addressed to certain email ids will be forwarded to JAMES. No further functionalities like relay/spam/virus etc are going to be configured in JAMES. JAMES is the final destination of those emails. There are some complex Business logic going to be implemented in Mailets including calling some web services etc. And ofcourse we will have to implement the error processing/re-processing etc. More and more tips from your experience is highly appreciated.. :) Thanks Mahesh On Tue, Aug 12, 2014 at 7:13 PM, Bernd Waibel wrote: > Right. > > Btw. > We use this "GHOST" state in our mailet, but always after writing a > comment to the log (like Mail from ... to .. with subject ... has been > deleted).

Re: Ignore email after processing
Thanks Stefano and Bernd. I am aware of the functionality of the mailets. Somehow I missed the GHOST state. Yes thats what I want. May be in the transport processor, I can have my custom Mailet instead of the following local delivery element.. And have my mailet take a decision on setting the state as GHOST/ERROR or something else based on the processing. Rite ?

Ignore email after processing
Hi, In certain mail servers like sendmail, we can pipe the incoming message to a script. Till the execution of the script, the mail will be stored in the spool queue. The mail will not get moved to the inbox after the script is run. So in effect the mail is deleted/ignored after the processing. If I want to implement this in JAMES using mailets how do I do it ? Can I prevent the email from going to the inbox of a user after processing the business logic in Mailets or can I delete it right after the processing ?. I don't want my inbox to grow. To give a background, I am implementing an email application platform; so there is no real users associated with this email server who want to manage their emails using any email client. And this is not meant to be a relay server as well. The email JAMES is going to recieve is forwarded from an Enterprise Email server. Please provide your comments/suggestions. Thanks Mahesh
Re: File Repository James 2.3.2
Thanks a lot Eric. That gives me more confidence on V2. I have built Postage from source and did a sanity run for a minute. I downloaded the source from http://svn.apache.org/repos/asf/james/postage/tags/james-2_20120613/ as opposed to the trunk mentioned in the wiki entry for Postage. Trunk doesn't have all the jars in lib. I will share the results once I do a load test with my expected load. And please expect more questions from me as I progress. Thanks again for the help/inputs so far.

Re: File Repository James 2.3.2
I will definitely evaluate v3. But our use case doesn't need IMAP. Its not a mail server which many users are going to access from their local mail clients. What we are planning is an email application platform where when an email is received over SMTP, call a web service and store the attachment in another cloud storage.The JAMES server will not relay the emails to any external mail servers. The mail flow ends when it arrives at JAMES. We have an enterprise email server forwarding the emails to this proposed James server. The earlier implementation was using a perl script which was configured through an alias file in SendMail. So essentially the sendmail+perl is going to be replaced with JAMES+Mailets. I have setup Postage and I am going to test the performance with the scenarios. But wanted an expert advice before I start testing them. Do you foresee any issues implementing this using JAMES 2.3.2 ? I know that the performance of the whole flow will depend on the implementation of Mailet. I wanted to know if there are any limitations or constraints etc with the out of the box features of JAMES 2.3.2 considering my use case ?

Re: File Repository James 2.3.2
Hi Eric, Thanks. I see that issue is fixed. I am going to use 2.3.2 which is the stable version. I cannot use v3 at this moment as its not stable and I cannot convince the people around here to go ahead with v3. Do you still see I would encounter these kind of issues with 2.3.2 ? What other options that I can explore in 2.3.2 ? I have read in the mailing lists about people using James 2.3.2 with huge load. Are you saying James is not a candidate for the specific use case that I mentioned earlier ?

File Repository James 2.3.2
Hi All, In the James v2 documentation it is mentioned as "File repositories are not recommended for large or performance-critical configurations." I am planning to use James 2.3.2 for a large and performance critical use case. I am expecting around 100K emails a day with a maximum attachment size of 20 MB (not all attachments will have 20 MB size). I have to strip off the attachments from the email and store in a File storage cloud. The above line about File repository really worries me. If not File repository, which other repository gives high performance and reliability. I don't think storing emails with large attachments in DB is a good idea. Please provide your inputs and guidance. Thanks Mahesh

Extend JAMES 2.3.2 JMX
Hi, Can we extend the JMX capabilities of JAMES by adding more MBeans ? The capabilities I wanted to start with is; 1. List the users 2. List the number of files in the Inbox/Error folder etc. 3. Move files from one folder to another Have someone done similar things ? Please share your thoughts. Thanks Mahesh
Re: Email to Cloud Use case
Yes Eric.. thats exactly I was planning to do; having the external service interaction before the mail is locally delivered. Spool will act as Queue in this case and Mailet will do the business logic and external service call etc.. and once the processing is done, the mail will be available in Inbox or Error based on the process outcome in the Mailet. I thought you were referring to implementing an internal queue (something like LinkedBlockingQueue) in the Mailet. Btw, I am planning to use 2.3.2 because its the stable version..

Re: Email to Cloud Use case
Thanks Eric. A queuing system definitely makes sense here. I am trying to understand bit more on the design considerations while using James. Spool itself is a queue. If I have enough storage space and the SLA expectation for processing the email is within a reasonable amount of time say 5 seconds, Can I have this functionality as part of the main processor itself ? Means, if I have an email in Inbox, that means the cloud service have been called for that email. Otherwise I can see the email in the error folder or something like that.. What are your thoughts ?

Commercial Support for JAMES ??
Hi All, I know JAMES is an opensource server under Apache License. I am finding it little bit difficult to convince my management to go with JAMES for our use cases. Do we have any commercial support available for JAMES ? Is someone providing or ready to provide the support. Please advice.. Thanks Mahesh
Re: Email to Cloud Use case
Thanks Ozgur. We are planning to have a it forwarded it to an ESB which has the queuing and other features in the next phase. If I implement the feature in the mailtet without a Queue, the messages will be available in the spool and will move to the inbox only when the webservice call is completed. Yes, Spool directory will get piled up depending on the performance of the Mailet and the number of spool threads configured. Do you see any other issue in this short term approach. If you don't mind, can you please share how you configured James to handle the errors/timeout etc in the WebService call ? Like moving to the error directory and reprocessing later etc ? What are the James related design considerations and best practices that you followed ?

Email to Cloud Use case
Hi, I am planning to use James Server for a Mail-to-Cloud use case. Here is what I am planning to do. 1. Receive email redirected from the Corporate Email Server to James (100K emails per day) 2. Do some validation/filter etc on the received email 3. Call the cloud web service with the email content and simultaneously, upload the attachment(max size may be ~15 mb) in the mail to another file storage cloud. I am planning to implement a Mailet for implementing this use case. My questions are; 1. What are all the design considerations that I should be looking at while implementing this ? 2. I may want to retry the emails which failed during the cloud interaction. How can I do this ? 3. Is anyone implemented a similar use case and can you please share your experiences ? I want to use 2.3.2 because it is the stable version as 3.0 is still in Beta and I cannot convince my company to use a software which is in beta version. Highly appreciate your thoughts and inputs on these. Thanks Mahesh
