Apologies my last attempt at this message failed to make it through. Hello All, I am attempting to get a windows OTRS 2.2.5 installation working for evaluation. I have configured my POP3 and SMTP settings and although I can receive emails I get this error when trying to reply. Traceback: ERROR: OTRS-CGI-10 Perl: 5.8.8 OS: MSWin32 Time: Wed Mar 19 11:01:09 2008 Message: Can't send to: user@email.co.uk! Enable debug for more info!
