Relay via Sophos Central

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!
