Relay via Sophos Central

prifesport

Hi guys,

I am currently switching from XG MTA to Sophos Central. Does anyone have experience with relaying via Sophos Central? I have no problems with Exchange. However, when I work with Telnet and EHLO, I do not get anywhere. It seems to me that the envelope is then not clean and the sender address cannot be mapped.

The goal is to have some existing Postfix systems relay via Central instead of the XG, does anyone have any experience with Postfix and Sophos Central?

Thanks in advance!
Stephan

     Thank you for posting into the Sophos Community. I think we need to establish what Sophos products you are referring to first.  Do you have Sophos Email and you want it to handle outbound emails coming from a postfix email server instead of the Sophos Firewall's MTA?
    Also what kind of "telnet and EHLO" test are you performing? And to which host name are you trying to use it on?
    I got Sophos Email AND Sophos Firewall MTA in my home lab and the first thing that I can say as a behavior if your Postfix email server is behind the Sophos Firewall is that it intercepts any port 25.. So if you are trying to communicate with Sophos Email from the Postfix email server, the Sophos Firewall will answer in return instead of Sophos Email.
    I think we need more overview information on this to assist you better. Thanks!
