Another SMTP question - Sorry

[jwoodyu]

I need to route outbound email through our email service provider. The provider like most requires a username and password authentication. If I choose SMTP over sendmail and define auth user and auth password does OTRS try to connect using that information? Or when electing SMTP does it require a smarthost that filters on IP etc?

Hi,

You have to specify the Host in the SysConfig SendmailModule::Host and sometimes the port too (SendmailModule::Port).

Both are defined and I am able to telnet to the host on port 25 so it is not firewall. hmmmmm

Hi,

Any related log entries? What's in the communication log?

Ok it is altogether strange. I checked it with a Thunderbird email client to make sure double sure the issue was OTRS. The client worked on 25 SMTP and 465 SMTP SSL. OTRS was set to use 25 SMTP to keep it simple. On a whim, I changed it to 465 SMTP SSL and it is working. Not going to look a gift horse in the mouth.

I have used OTRS Community since version 3 and this is just a fresh rebuild, starting over for a small helpdesk.

Thank you for your help,

John
