Enabling SPF checking on on Scalix Relay SMTP?

[eightysix]

Having SPF detection problems, here we have a Amavis setup on a Scalix system working just fine, but we now would like to enable SPF checking, it does not work inside of Amavis due to Scalix Relay SMTP pushing to the Sendmail SMTP setup, making it impossible for the Amvis to detect the sending E-mail server, for SPF records checking.

Has anyone enabled SPF checking on a Scalix system, and how did you do it?

In this case, you'll need to make sendmail with amavis your primary SMTP listener. This can be done, however, you'll lose the ability to have standards-based SMTP clients to authenticate against the Scalix server.

Scalix 11 SMTP relay can be configured more flexibly, you'll then be able to have it listen on the submission (believe its 587/TCP?) port for internal users and SMTP authentication and leave port 25 for sendmail for better integration of advanced Anti-Spam such as SPF.

Hope this helps,
Florian.
