this is clearly a network-layer problem
what says "ping 65.55.92.184" from this machine and other ones?
Hi,
You're not on a RedStation dedicated server are you, per-chance? The
reason I ask, is that I encountered this exact error yesterday and
investigating into it with a tcpdump, showed RedStation's gateway was
filtering SMTP connections, forcing it through their own (exceptionly
poorly configured) relay. The response I was getting back when
attempting outbound port 25 connections was 'no route to host'.
This is very annoying as I've had to smarthost mail through a different
box on port 587, to avoid their relay! Was not made aware of this before
purchasing the server and it's not in their T&Cs.
Cheers,
Duncan.
