That's the weird part - the logs show *nothing*. I see a log entry from my
DSL router showing the incoming port 25 connection being directed to my
Linux box, and then that's it. No message from postfix or anything. If I
try telneting in from the Windows box on the same home network, I likewise
get no notation of any connection showing up in the syslog. This never
happened with 8.2 or below.... <mumble>
I checked, and /etc/hosts.{deny|allow} is empty, other than the comment
lines telling what the files are for.
How would I check for an ipchains (or whatever) rule, to see if somehow
port 25 connections are being blocked at that point? Yes, I'm probably
clutching at straws here, but you never know....
