Sender rewrite scheme wont work on Fortimail 7.2.0

[FortiVoid]

Hi guys,

my setup:

• FortimailVM04 V7.2.0
• gateway mode
• relay to O365 tenant

Currently, the relay and so on works fine. Only the SRS (Sender rewrite scheme) don't apply. The Envelope-From address won't change. The official documentation just say activate and that's it. So if anybody hast some info or has experience with the SRS feature, please help me.

Thanks in advance

What have you configured under Security > Sender Rewriting Scheme > Setting?

Domain for rewrite -> all domains

rewritten address handling -> none
