I was wondering if anyone else figured out a way to re-write the SMTP header information for all outbound emails. Specifically, I am interested in stripping out the internal mail server's IP address and replacing it with the external IP address of the firewall. I am pretty sure that Astaro does not natively support this feature; however, I am looking for a work around at this point.
Anyone have any luck with this?
TIA!
Mike
