localhost port 25 not open
 
OK, I'm tired, and a bit confused. Made some network and hardware changes, and now I can't get the mailserver to work. It seems that sendmail can't loop to itself on 127.0.0.1. When I nmap localhost, I find that port 25 isn't open.

Naturally, nothing has changed on my system except for different routing, interfaces, etc.

So the question for sendmail gurus,is where should I be looking?

Thanks.

Well if you've changed network and hardware then why should that be a sendmail thing? You need to divide and conquer etc... Is sendmail running at all? Is it listening on port 25? Note that iptables can still happily block a connection if it is listening just fine etc.

port 25 issue resolved, I think.

Now have an smtpauth problem. But I can ping smtpauth from another machine on the lan, so this is probably a routing problem...looking

So post the details of what it was you did to solve it.

That way in future when people come across this thread via Google when trying to find a solution to their own problem, details of your solution might help them.

I wish I could tell you exactly what I did to solve it. The several sheets of scribbled notes. In the end I got it fixed, but could not duplicate it if I had to. This is a direct consequence of having too many things going at the end of the effort. Sorry.
