Sophos UTM / DMZ / Mailserver / SMTPTLS not working

Technik Onkel

Hello, 

i am using UTM as virtual appliance. I have setup a DMZ Interface. Which works fine.

 

I now installed a Ubuntu Server in DMZ. Its using OTRS.

I can not send mails outgoing. OTRS can receive mails from external servers.

Virtual machine has DNS and Internet access.

 

I think OTRS configuration is fine. I now need to check the UTM configuration.

I have a masquerading rule for DMZ to External

I have a firewall rule for DMZ outgoing Any Any
