Hi all,
I have mail/postfix working in conjunction with mail/dspam on my server.
Postfix pipes a mail to dspam, the latter scans it and returns it to postfix via an alternative port, in this case 10026. Postfix then delivers the mail. This is a fairly standard config I believe. Here is the relevant entry in master.cf:
This works fine.
I also use this alternative port (10026) for outgoing mail which doesn't need to get scanned by dspam.
For my mailserver on my LAN, I had email clients also use port 10026 for outgoing mail, and enabled is like this:
For a mailserver on a remote host, I am trying the same, only this time adding an external IP number:
I've also added that external IP to main.cf in "mynetworks"
But it doesn't work. I've opened 10026 in PF:
But when I telnet in, I don't get the postfix prompt:
This is what I see when I try the same on the server:
For some reason, postfix appears to refuse an incoming connection on port 10026 from my IP number, even though I've explicitly enabled it. Any ideas why?
