Hi, i configured OTRS via SMTP relay/smarthost it's working fine except for emailing as a response to a ticket or composing a email manually. The automatic response email works, so I assume sending emails as reply to a ticket would work to but I get the following error : Fout: Can't connect to smtp.office.firstfind.nl: Invalid argument! Terug traceren: ERROR: OTRS-CGI-10 Perl: 5.6.1 OS: linux Time: Wed Sep 1 10:58:23 2004 Message: Can't connect to smtp.office.firstfind.nl: Invalid argument!

I just can't think of anything that's causing this error Thanks in advance, Jeroen Bosch
