Re: [Shorewall-users] Yahoo mail connection issue
Nigel, Thanks for the response, that was my first response to the problem. The problem that I'm having is that I can't find any trace of a connection attempt in either my mail server log nor in my shorewall log. If the connection is being made to my fire wall I can't figure out how to detect it, i.e. what should I look for? I must confess that the info that shorewall logs is to say the least daunting and to my eyes rather obscure I've tried lining up the time of the email with the appropriate time in both logs but unfortunately don't see any correlation.

I have this rule in place for my email DNATnet loc:192.xxx.xxx.16 tcp http,https,imap,imaps,smtp,smtps My problem is that whenever someone using an AT phone or form Bellsouth.net sends me email it fails and the email is returned to the sender as failed with this error "Mail server for "geenhuizen.net" unreachable for too long" Apparently both AT and Bellsouth use yahoo mail service, however if someone on Yahoo mail sends me an email it works just fine. I've looked through /var/log/maillog but can't find the connection at all, and I can't find any connection in the shorewall logs either. I must confess that I don't know what to specifically look for in the shorewall logs. So what to do?
