Re: [IMail Forum] Imail Listserv

[IMail Forum] Trailer.txt for a specific domain.
Hi: Thanks for the reply-- Just a quick question about the topic again. We host a number of virtual domains and we want to put a trailer only for one of these domains. According to the IPSwitch site- Question/Problem: Is it possible to include a footnote in every e-mail sent by any user, like thanks for using IMail? Answer/Solution: If you create a text file named trailer.txt in the \imail directory it will be appended to all outgoing messages. Please note: the trailer is not appended to messages sent locally (to other mailboxes on your IMail server). Also, mail clients may not see the trailer if it is appended to HTML formatted messages. Set your mail client to use Plain Text (that is, the Content-Type will be text/plain). -- If we add this to the Imail directory- would it not then send it to all domains?

[IMail Forum] Switching from an External to the Imail database!!!
We have a couple of domains that presently use a MS SQL database.

Has anyone done this before and if so what are the steps? I have searched the knowledge base and have not come up with anything useful. A small rant - The inability for IMail to perform SMTP authenicate with IPless domains against an external database is a MAJOR FLAW - it sticks one with having to burn an IP with every domain or mixing Imail database and the external database.

[IMail Forum] SMTP Relay. What can we do better.
If anybody has any suggestions on how to handle this I would be very appreciated. We are using Imail 7.x and have around 100 domains. We are a small ISP providing web hosting and email services for small to medium size businesses. Last week, a person was able to relay 300,000 emails through our Imail server. Our current relay is setup for USERS only. The person was able to relay mail through our system by changing his computer name to a domain name in IMail, and creating an email account on his computer the same as an email account in one of our Imail domains. Since IMail was setup for RELAY FOR USERS ONLY, everything worked correctly. Even if we had setup IMail relay for HOSTS ONLY, the same thing would have occurred. We tried the NO RELAY option, but unfortunately, since the accept.txt file does not work for NO RELAY, none of our emails from WhatsUP Gold could be sent, and some of our third party applications like FrontPage etc... cannot use SMTP Authentication. It would be nice if the ACCEPT.TXT file would worked for NO RELAY but it doesn't. Accept.txt only works for HOSTS and USERS only. If accept.txt did work for NO RELAY, we could put the IP addresses of our internal systems in this file, and all users would then be required to use SMTP Authentication. Problem Solved. I'm a little upset about this because it was pretty simple for this person to do this and if any person reading this email uses NO RELAY for HOSTS or USERS, you are also susceptible to this relaying as well. So what does one do ? Please help !!! Sincerely, B. Williams. Please visit http://www.ipswitch.com/support/mailing-lists.html to be removed from this list.

[IMail Forum] SQL problem
Hi there: Well, im running Imail Server 7.04 HF2 and i have an external database for my users (1 users in SQL database). The thing is that in imail V. 5.06 the database worked fine, it tooked out like 1 minute to load it and then no problem, but in Version 7, the database takes like 5 minutes to appear and then suddenly more users start to appear between the ones that have already appeared and its almost impossible to edit the users. Well, thanks for your help. Sergio Rincon
RE: [IMail Forum] SMTP Relay. What can we do better.
You can do exactly what your asking for, but you need to set it up a little differently: - Set your relay options to: Relay for Addresses - Press the Addresses button and enter your internal systems (you only need to include to servers that cannot do SMTP AUTH and which need to send SMTP) - Set all clients to use SMTP AUTH REMEMBER: The only safe relays options are no relay and relay for addresses. Using relay for users allows user spoofing and will get you on the RBLs very quickly (as you have experienced).

Re: [IMail Forum] SMTP Relay. What can we do better.
Last week, a person was able to relay 300,000 emails through our Imail server. Our current relay is setup for USERS only. So you were allowing him to send spam. The person was able to relay mail through our system by changing his computer name to a domain name in IMail, and creating an email account on his computer the same as an email account in one of our Imail domains. No, it's not nearly that difficult. In their spamware, when asked What address do you want listed as the sender of the E-mail, they just entered [EMAIL PROTECTED]. No changing of computer names, no creating E-mail accounts, no hacking involved. Since IMail was setup for RELAY FOR USERS ONLY, everything worked correctly. That's correct. Relay for users means that you will let anyone relay if they have an account on your server, or are willing to use an E-mail address on your server. Even if we had setup IMail relay for HOSTS ONLY, the same thing would have occurred. Quite true. Relay for hosts means that anyone can relay mail through your server if they have an account on your server, or are willing to use a made-up E-mail address on your server. We tried the NO RELAY option, but unfortunately, since the accept.txt file does not work for NO RELAY, none of our emails from WhatsUP Gold could be sent, and some of our third party applications like FrontPage etc... cannot use SMTP Authentication. With No Mail Relay, you don't use accept.txt -- it means that everyone has to use SMTP AUTH. Relay for Addresses does what you are looking for (although you don't use the accept.txt file, you use the button next to Relay for Addresses to list the safe IP addresses. It would be nice if the ACCEPT.TXT file would worked for NO RELAY but it doesn't. No. No mail relay really means Only relay for people using SMTP AUTH. If IMail let certain users bypass it, then it would be Relay for Addresses (which it already has). I'm a little upset about this because it was pretty simple for this person to do this ... The problem is that IMail doesn't make it clear that several of their anti-relay options don't prevent spammers from using your mail server. The Relay for Users option isn't designed to stop spammers. -Scott --- Declude: Anti-virus, Anti-spam and Anti-hijacking solutions for IMail. http://www.declude.com Please visit http://www.ipswitch.com/support/mailing-lists.html to be removed from this list.

Re: [IMail Forum] Switching from an External to the Imail database!!!
We're currently using a SQL database for one of our clients in Imail with SMTP authentication.

Here is the problem. Imail does not perform smtp authenication on virtual domains that share an IP address.

[IMail Forum] CurrentDomain and User Administration
-- Original Message -- Interesting. You're saying there must be a host alias that matches the exact hostname in the URL used to access webmail? Yes, It does appear that way. However, problems still exist with me being able to only display or modify a user that has a host administrator attribute. If I try modifying or diplaying any other user, I am returned to the login screen. It appears as if the IMAIL.BeginIfHostAdmin tag is holding the value from the user I am editing rather than the currently logged in user. That's a known bug with 7.04, introduced after Ipswitch beefed-up template security a bit too aggressively. We've fixed it in our templates, but stock templates remain broken. You're correct, in that IMail is interpreting that tag from the perspective of the user being displayed or modified, not the perspective of the logged-in admin. Whoops. To fix it, you need to REMOVE those IMail.BeginIfHostAdmin starting and ending tags from the dispusr.html and chguser.html files. Yes, thank you, I got that to work last night, but I made a slight change... I kept the IMail.BeginIfHostAdmin and changed it to IMAIL.BeginIfUserHostAdmin where it tries to determine if you're a system admin or host admin. Then, where it displays the checkbox for host admin, I changed that from IMAIL.BeginIfUserHostAdmin to IMail.BeginIfHostAdmin. (I just reversed them) Anyway, hopefully that will take care of those problems until they release a patch where I'll have to change it back. Don't they test before releasing? It's not like it's a hidden bug or anything... pretty obvious. Anyway, thanks for your help.

Although not the best way, I am currently using Relay for local host only, with Declude Hijack running in back ground. It has solved problems we have had in the past.

No changing of computer names, no creating E-mail accounts, no hacking involved. Since IMail was setup for RELAY FOR USERS ONLY, everything worked correctly. That's correct. Relay for users means that you will let anyone relay if they have an account on your server, or are willing to use an E-mail address on your server. Even if we had setup IMail relay for HOSTS ONLY, the same thing would have occurred. Quite true. Relay for hosts means that anyone can relay mail through your server if they have an account on your server, or are willing to use a made-up E-mail address on your server. We tried the NO RELAY option, but unfortunately, since the accept.txt file does not work for NO RELAY, none of our emails from WhatsUP Gold could be sent, and some of our third party applications like FrontPage etc... cannot use SMTP Authentication. With No Mail Relay, you don't use accept.txt -- it means that everyone has to use SMTP AUTH. Relay for Addresses does what you are looking for (although you don't use the accept.txt file, you use the button next to Relay for Addresses to list the safe IP addresses. It would be nice if the ACCEPT.TXT file would worked for NO RELAY but it doesn't. No. No mail relay really means Only relay for people using SMTP AUTH. If IMail let certain users bypass it, then it would be Relay for Addresses (which it already has). I'm a little upset about this because it was pretty simple for this person to do this ... The problem is that IMail doesn't make it clear that several of their anti-relay options don't prevent spammers from using your mail server. The Relay for Users option isn't designed to stop spammers. -Scott --- Declude: Anti-virus, Anti-spam and Anti-hijacking solutions for IMail. http://www.declude.com Please visit http://www.ipswitch.com/support/mailing-lists.html to be removed from this list.

[IMail Forum] Outlook Calendar Share? Outlook Address Book Export?
Hi All I just got the imail software through my webhost and it looks really good, but the only problem is that the boss has over 2000 contacts in outlook and would like to be able to access them when she is using the webbased version of imail. Is there a way that we can do that and not have to enter them manually as this would take forever! Someone may have seen a batch file or something like that, which will make my life simple. Secondly, is there anyway that we can synchronize the information in Outlook calendar with the calendar function of Imail? I hope there is as this again will be very useful (and may help me keep this new job which I just got!) so please help me solve this problem and if you can't help maybe you know someone who can, please fwd this to anyone you think that can help me keep my job!!!

[IMail Forum] I think my post was overlooked because someone appeared to answer it
So here it is again. Hi. We have Imail 6.06 running an external db (SQL Server 2000). Imail is part of an entire web-based application written in ASP that has, among other things, a contact database. We want to allow our users to be able to create lists of their business contacts. Once a List has been created, the user should be able to send an email to everyone on that list. We decided we would use Imail's built-in mailing lists for this. So we've created the lists where we capture the email addresses of everyone and we can write out those addresses to the right file in the Imail directory so it creates the mailing list. BUT, it seems that in order to work, there is another file that contains a list of all the lists that we have to write to. This wouldn't be a big deal, except that we're worried about contention. Since we have 400+ users, and since each user essenitally can create their own mailing lists, it's possible that multiple users would be writing to that one file simultaneously. We're wondering if someone has a work-around for this, an API or something that allows multiple users to create lists simultaneously. Thanks for your help.

Re: [IMail Forum] Switching from an External to the Imail database!!!
Yes: I fully understand that. That is a problem for us - means that we will be mixing our users between external databases and internal databases. Back to the original question. Has anyone ever converted a domain from using an external database to using the Imail database. 1) Is it as simple as just selecting the radio button (doubtful)? 2) Do I convert the domain to the Imail database and add the users back to the domain manually? 3) Do I totally blow away the domains and reconfigure (ouch)? I am guessing that option 2 would suffice but am skeptical. Thanks for any help.

Re: [IMail Forum] I think my post was overlooked because someone appeared to answer it
Due to self imposed list limitations already present in IMail, you might consider using a stand-alone list server for the purpose you outlined below. Listar running on say RedHat 7.2 would easily meet your needs, and the custom interface and scripts would be easier to create and maintain. IMail itself would choke if too many of those users decided to use their lists at the same time, but Listar with Postfix as the MTA would easily process anything those users could send it, or at least up to your hardware's capabilities. In this case the time spent to develop this solution might be wasted when you find IMail choking when trying to process the lists.

Re: [IMail Forum] Switching from an External to the Imail database!!!
Jeff: I assume that you mean that it will do smtp auth on shared IP domains on an external database. My understanding is that this only works if the primary domain on the server is using the Imail database - if that is not the case let me know as this would be a major solution for us.

There are a couple of these messages that bring up a good point that I'm unsure of: when you use relay for address, how do you handle clients when you don't know their IP address?

RE: [IMail Forum] SMTP Relay. What can we do better.
There are 2 solutions here that work independently, but in concert. 1. SMTP AUTH works all of the time. As far as I know, it cannot be turned off. It is independent of the relay setting. It is independent of the IP address. And the address can change anytime. All it needs is a connection to port 25 of the IMail server. The client will send credentials to the server for authentication on each SMTP session opened (basically, each time a message is sent). 2. The relay setting: If you use No Relay, you can still have clients send SMTP messages by using SMTP AUTH (remember, it can't be turned off). Using Relay for Addresses is essentially a whitelist of IP addresses that can send SMTP messages throught the server (relay) without requiring authentication. Typically, these are machines that run automated processes that generate email (i.e. not typically your domain controller). These are also addresses that typically reside inside the firewall. This keeps them from being spoofed. If you choose, you can specify a public IP address (like a client's server, or perhaps their firewall public address if they are using NAT), but it may be possible to spoof this address (b/c you have no control of what goes on out in the big, bad world). Summary: By using Relay for Addresses, you allow a unknown number of clients with unknown IPs to relay after being authenticated and you allow a known number (keep this list as small as possible) of machines to relay without authenticating. Be sure that you trust any machine on the address list!!! Hope this helps.

Re: [IMail Forum] SMTP Relay. What can we do better.
Hey Todd, Very clear explanation. Now the question becomes: is SMTP AUTH really on all the time? In Outlook Express, there's an option, server requires authentication for ourgoing (SMTP) mail, on the Server tab of the Account Properties dialog box. If this is unchecked, doesn't that mean the client will connect without SMTP AUTH?

RE: [IMail Forum] SMTP Relay. What can we do better.
My previous explanation was purely a server side perspective. For the client - If the server requires SMTP AUTH (which it should by now!!!), the client has 2 choices: (1) Do not supply authentication credentials; in which case the server will deny all relaying attempts by this client. Typically reported to the user as error relaying denied by this server: xxx.xxx.xxx.xxx or something like that. (2) Do supply authentication credentials; in which case the server will authenticate the client and if authentication passes, allow the SMTP relay (sending of outgoing message). To accomplish #2 above: You need to setup your client to login (send credentials) when attempting an SMTP relay (sending a message). In Outlook/Express, you need to goto Tools/Accounts, open the DEFAULT account (this is the one that has (default) next to the mail type, there can be only one default and this is the account that will be used to send all outgoing mail), then on the Servers tab check the My Server Requires Authentication box. It normally defaults correctly, but you can press the settings button, then verify that the Use Same Settings As My Incoming Mail Server radio button is selected. IMail server cannot use different credentials for POP3/SMTP on the same user, so as long as you set the POP3 server and SMTP server to the same IMail machine, you must use the Use Same Settings As My Incoming Mail Server radio button selection.

I've never used IMAP, but I'll take your word for it on that. :-) Does that mean that you would have to select the SMTP server to use for each outbound message? Sounds like a pain to me.:-( I prefer the POP3 method of selecting the outbound account and knowing that all messages will go there without doing anything other than pressing send.

RE: [IMail Forum] SMTP Relay. What can we do better.
Today our host informed us that he is instituting the no relay you all have been mentioning. He also said that was for security reasons to avoid any chance of spoofing and therefore connecting via the IP addresses in a list would be the ONLY way that we could collect our mail. He said that would mean that when I go on the road, I will no longer be able to collect my mail via my Mindspring dialup number, which I keep for traveling purposes. He said we MUST use Imail's web mail when not at our regular computer and at our regular host. But if I am reading this correctly (it is difficult for me to understand), he is wrong. He should turn off all relaying and then our email programs will do SMTP AUTH which means that someone would have to have my email password to send mail via our domain. That would mean that I should still be able to collect my mail via Eudora while logged into other ISPs, including Mindspring while I am on the road. That is, as long as my mail client has the Authentication Allowed box checked. Am I correct? I am no nerd, so please be gentle.

Re: [IMail Forum] I think my post was overlooked because someone appeared to answer it
I have built a similar architecture and have three things to say in response: 1) The... file that contains a list of all the lists that we have to write to ...is not necessary to send mail to lists. You don't need to update LISTS.TXT unless a) you're interested in presenting your list names via IMAILSRV's LIST command or b) you absolutely, positively, must use this file (and--hint--not a multi-user database) to present an accurate list of lists via the native Imail web admin interface (not--another hint!--via a page gen'd by your proprietary app). 2) You *do*, however, need to be able to add your lists' program aliases to the Imail Registry, though I presume you already have this functionality via VBScript or are using the command-line ADDLIST. Luckily, the Reg is sufficiently multi-user. 3) Be attentive to concurrency issues when writing out the USERS.LST file. Yes, it *seems* like only one user will be writing to each file, but what if that same user is logged in twice...control for this in your code or it may be a problem. Time out the file open to make sure it gets closed if a session times out. Also, open it as shareable read write when updating it, so it can also be opened simultaneously for reading by the IMAILSRV process if necessary. Contrary to what Todd suggested, I see no reason not to do this on Imail. You haven't told us how many users you expect per list, but if each one is just one person's legitimate opt-in contact list, I can't see it being a problem, given sufficient server hardware. He's certainly right that with big public lists, Imail's not up to the task performance-wise. Of course, that's why we (Broadleaf Systems) are writing a substitute (see my other post)!
