Hi all. Due to the demise of the Sixxs project, which I was using to bypass the ISP’s filtering of port 25 (in/out), I would like to open a "private" port on postfix. It’s a non-standard port and I will be filtering the src range at firewall level so I’m pretty confident there will be no abuse. I also want to avoid adding the subnet to mynetworks since I find it easier to work on the firewall rather than the mail server.
I was able to have postfix listen on the new port but I realized all sender and client restrictions are still being enforced despite passing a <permit> directive: XXXXX inet n - - - 250 smtpd -o smtpd_client_restrictions=permit Furthermore, the server advertises a whole bunch of stuff I don’t really need (at least not on that port): 250-VRFY 250-ETRN 250-STARTTLS 250-AUTH PLAIN LOGIN 250-AUTH=PLAIN LOGIN What is the correct configuration to provide a bare smtpd process that will accept all mail on that specific port and treat it as if it was coming from a mynetworks host? Thanks!
