Hello, I am looking for SRS solution for Postfix, as in SPF-compliant world lack of this breaks forwarding from my site. We use Zimbra, so hacks with .forward file or /etc/aliases directing to "| /usr/bin/srs ..." will not work. I am going to either install SRS software on Zimbra MTA, which is Postfix controlled by Zimbra configuration scripts, or on outgoing mail gateway - also Postfix now.
I realized that Postfix can support SRS through milters. Can you recommend me any SRS milter, stable and known to work with Postfix (not employing protocol features present only in Sendmail)? Eventually I can switch to another edge MTA, but if this is possible, I will stay with Postfix. I suppose that the question isn't too original, but I have found surprisingly few information on the web, and mostly outdated. Thanks Hieronim
