SMTP Relay with two mail domains

Hi

I had a question about the SMTP Relay on my XG 135 Firewall and it works correctly, now. At least with one mail domain external mail server secured over xg firewall (solved).

I increased the complexity with a second mail domain and get an error.

My General email settings are:

I have two SMTP/SMTPS policies, one for every mail domain. The business one is the same only with their own domain name.

The address group for both domains are the same with the difference of the domain name:

I just show you how i create this for both domains. At least for the privat it's working.

 

Problem:

If i send from a third mail account a mail to both mail accounts (privat and business) is on one a crazy mail delivery error.

Both mail accounts are by the same provider, one was successful the other wasn't. I think it is not possible to relay more than one mail domain over the XG Firewall with the newest SFOS V18. The best would be i made a configuration error :). Attached the error message:

This message was created automatically by mail delivery software. A message that you sent could not be delivered to one or more of its recipients.
This is a permanent error. The following address(es) failed:

  • My interpretation of the error message is for following part:

    Received: from [180.100.244.237] (port=60360 helo=privat.com) by hos108.unaxus.net

     

    There is a helo according the "Email/General settings" with privat.com, it works for the private mail domain but not for business mail domain. I think it should be "helo=business.com".

     

    In "Email/General settings" is only one domain allowed, as far as I see.

     

    How can i solve this problem?
