SMTP relay with more than one domain

Hello

I don't know if there is a solution. I placed this question already on the Sophos Email part of this community, but didn't get an answer.

I have to relay two mail accounts with two different domains (mail.private.com, mail.business.com). They are both by the same provider.

I made my first expierences with relaying of the first one and it's working - external-mail-server-secured-over-xg-firewall .

I tried also to integrate the second mail account (mai.business.com) and i got error message. One feedback which i got was that more than one relaying are possible, but the result is an error with a message i don't understand. See also the question I placed at community - smtp-relay-with-two-mail-domains

  • Hello Wolfgang,

    Thank you for contacting the Sophos Community!

    It seems like the XG is blocking the IP, can you create an exception in the Email Protection for this IP 180.100.244.237.

    IF I am reading correctly this was trying to send the email inbound to your server? 

    Can you provide the output of the smtpd_main.log when this issue happens?

    Regards,
