[HECnet] TOPS-20 outgoing mail relay config

I was able to get outgoing mail working without TOPS-20 being the wiser. I'm now running "redir" on my local emulator host (linux) to listen on port 25 and send all connections to my external mail server (a site out on the Internet) on port 2525 (I set postfix to listen on port 2525 in master.cf, in addition to the default). Then, on my local firewall, I'm using iptables to send ALL outgoing connections to any host at port 25 as a PREROUTING NAT rule to be diverted to my emulator host's port 25, to hit the "redir" process. In this way TOPS-20 can send mail to any valid e-mail address and have it transparently diverted to my external mail server's port 2525, where, subject to postfix's approval, it will deliver the mail. It just took some ingenuity to work around Comcast's silliness. -Mark On Mon, Feb 3, 2014 at 11:08 PM, Cory Smelosky <b4 at gewt.net> wrote: On Mon, 3 Feb 2014, Mark Abene wrote: Here's the path madeline.gimme-sympathy.org takes: (4.3BSD running qmail.

The return path is MUCH simpler. Where's the mailer config on TOPS-20 located? -- Cory Smelosky http://gewt.net Personal stuff http://gimme-sympathy.org Projects
