[xmail] Help about slow mail sending (could it be Xmail configuration related, or not?)
Hi all I use xmailserver since many years withou any kind of trouble, but since few months I'm experiencing some oddness in mail sending, so I'm here to ask you help to understand if it can be related to xmailserver wrong configuration, or if it depends on other stuffs. The problem I have is the excessive delay in mail sending when using php scripts to send an email. The machine is win2000 server, with php 4.4.9 and IIS 5 Using a standard mailer client (outolook, pegasus or any other one), all seems to go fine (I can't see any delay in mail sending) When I try to use a script, I have the delay. I have tested it in various scenarious: 1) NOCC webmail interface: if I write an email using a web browser, after sending it I have ~30-35 seconds of delay before receiving the next webpage indicating that the email has been sent. 2) joomla websites: after completing an order or filling & sending a form, the confirmation webpage (shown when the mail associated to the order or to the form has been sent) arrive to my browser after ~30-35 second of delay 3) os commerce websites: the same as point 2 I'm not a mailserver and php scripts expert, so I can't understand if this situation may be related to something wrong in xmailserver configuration, or to normal operation performed by the system (i.e., a delay due to the time the mailserver requires to reach and scan the internet spamlist we use to reduce spam) or to any other possible wrong configuration in my system. My goal is to reduce this delay to a reasonable time: I have to setup some ecommerce websites, and I can't ask to the customer to wait for 30-40 seconds before receiving a reply from a website :-) I hope someone could help me :-) Thank you in advance Regards ___ xmail mailing list xmail@xmailserver.org http://xmailserver.org/mailman/listinfo/xmail

IMO such delay is related to DNS queries, either to get the host name attached to the local XMail server IP, or to resolve CustMapsList queries. Try to disable RDNS checks inside the server.tab, and also empty CustMapsList, and see if it helps. If it does, your DNS/network config is the problem. - Davide ___ xmail mailing list xmail@xmailserver.org http://xmailserver.org/mailman/listinfo/xmail
[xmail] Smarthost
I'm a total xmail newbie so I'm struggling a bit with the basics. I am trying to set up xmail on an embedded platform running linux. The machine in question will collect information and periodically email a status report via a smarthost. The platform has a sporadic connection to the outside world. I'd like to configure xmail to 1) spool any email it receives from the internal network 2) on connection, run the queue (this will be handled by the ifup script) The smarthost uses TLS and requires authentication. How do I configure xmail to do that?

You can just collect your information and shoot an email to the smart-host when the connection comes up (via post-up scripts). IMO no need to setup a mail server. - Davide ___ xmail mailing list xmail@xmailserver.org http://xmailserver.org/mailman/listinfo/xmail

I've been struggling with that. But the smarthost requires TLS authentication, and what with spooling the messages and then sending them, it's a bit of a stretch for me to write all that in a script. Plus the whole thing of retries if the connection goes down in the middle of a transmission, and all that. I was hoping to find a ready-made solution and nothing else seems to support both spooling and SSL and presumably retries if the message send fails. --Yan -- o__ ,>/'_ o__ (_)\(_) ,>/'_ o__ A day may come (_)\(_) ,>/'_ o__ when the courage of men fails, (_)\(_) ,>/'_ o__ when we forsake our friends and break all (_)\(_) ,>/'_ bonds of fellowship, but it is not this day.

For SSL, there are modules (Perl, but I bet you can find them in almost any scripting language), like: http://search.cpan.org/~gbarr/libnet-1.22/Net/SMTP.pm http://search.cpan.org/~cwest/Net-SMTP-SSL-1.01/lib/Net/SMTP/SSL.pm http://search.cpan.org/~fayland/Email-Send-SMTP-TLS-0.03/lib/Email/Send/SMTP/TLS.pm They support TLS and ESMTP authentication AFAIK. If using XMail (that IMO is overkill for this), you will need to setup a queue retry policy so that messages live in the queue long enough to see a connection coming up. Plus, you will still need to issue an ERTN command to flush the queue while the connection is up. - Davide ___ xmail mailing list xmail@xmailserver.org http://xmailserver.org/mailman/listinfo/xmail
