Sophos Smarthost - Outgoing Interface + NAT

Hello,

an XG uses a smarthost in the upstream to send and receive mails towards the internet.
My problem is that the XG sends outgoing mails already on the right interface, but here is a transfer network towards the smart host, which is private and not public, the upstream smart host knows no route to the IP that the Sophos uses.
I have already tried everything with NAT, but nothing seems to work here.

Help :)



This thread was automatically locked due to age.
  • So, the connection is okay now, but it seems there is another issue with mail-protection itself, according due to the mail delivery to the upstream smarthost.

    In the General config tab I disabled nearly anything that would scan or block something. In the log file I just can't find the error why the mail is still bounced now.

    Trying to send via Outlook from  Test.User@internal-test-domain.com TO test@sophos123.com (does not exist)
