I've installed OTRS on a Debian-based Linux Distro and, fortunately, everythings goes okay (so far), except for a delay I get when performing an operation which relies on e-mail sending functionality, like answering a customer ticket. I run it on a MS Exchange Server, in an intranet.
Check system logs to see what actually happens. Does the mail get spooled locally? Are you connecting directly to the MS Exchange Server or going through SMTP running at localhost as well? If you know the SMTP protocol, try telnetting to the SMTP server and send an email manually. Maybe there some greylisting or virus scanning involved on the Exchange side? Other culprits may be (and often is!) DNS lookups timing out. Make sure you have only responding DNS servers defined. What do you really mean by delay, btw? Are we talking seconds, minutes or hours here?
I think OTRS might be performing some kind of checking before actually sending the mail. If that's the case, what would that be? Have you ever experienced that?
That may well be what Maurice is drawing out in his email. Try turning off the MX checking and see if that changes anything? It's the CheckMXRecord setting in Framework -> Core under SysConfig. Marius
