[otrs] SMTP Problem

Hello - I have recently installed OTRS and it is a fine trouble ticket system, however I am having problems getting the email notifications to work on the FreeBSD system which I installed it upon. I know that SMTP works fine on the system since I have various other apps which use SMTP port 25 etc .. I am simply looking for my technicians to receive a notification when a new trouble ticket is created in the queue. I setup OTRS to use SMTP and not sendmail but it just seems that the software refuses to send out the email. -- Glenn Campbell
