We did try switching to the "Sendmail" option under Core::Sendmail::SendmailModule, but it didn't seem to make a difference (still saw long page delays). Do you mean we should set it to use the SMTP option under Core::Sendmail::SendmailModule and send via tcp/ip rather than directly to the sendmail binary?
Thanks,
Jeremy

Subject: Re: [otrs] OTRS vulnerable to slow mail relay
* Porier, Jeremy
Does anyone have suggestions for ways I can make OTRS less susceptible to a slow smtp server? We are forced to relay through a single outbound host (which I have configured in sendmail) that sometimes gets a bit overwhelmed (it's also the main spam filter for a large number of mailboxes). Yesterday it was causing page submissions to take two minutes or more as it processed all of the mail notifications. It made for some frustrated customers and agents.
I'm hoping there is a way to have sendmail instantly queue the messages, which would allow the web pages to continue on quickly, but I have zero experience with sendmail so it may just be a naive hope.
Configure OTRS to use your local sendmail or postfix installation (127.0.0.1) sendmail or postfix can then queue all mail and use the aforementioned "single outbound host" -- Ralf Hildebrandt Geschäftsbereich IT | Abteilung Netzwerk Charité - Universitätsmedizin Berlin Campus Benjamin Franklin Hindenburgdamm 30 | D-12203 Berlin Tel. +49 30 450 570 155 | Fax: +49 30 450 570 962 ralf.hildebrandt@charite.de | http://www.charite.de --------------------------------------------------------------------- OTRS mailing list: otrs - Webpage: http://otrs.org/ Archive: http://lists.otrs.org/pipermail/otrs To unsubscribe: http://lists.otrs.org/cgi-bin/listinfo/otrs
