I have been puzzled over this for a while and do not know what causes the
problem or what is really happening.
I have two internet mail relay servers, let's call them mr1 and mr2. Both are
identical in configuration but have different host names and ip addresses are
running simultaneously. Every now and then I notice that some incoming mail is
stuck in mr1's mail queue because it tries to contact/send the mail to mr2
where it times out. Something like:
6E60C5F3CAF 2784 Wed Nov 23 10:26:04
tis...@yahoo.com<mailto:tis...@yahoo.com>
(connect to mr2.junk.com[xx.xxx.xx.xx]:25: Operation
timed out)
My question is why does this happen? Why does mr1 try to connect to mr2 where
it times out for some reason? Why does it not accept (receive) the (incoming)
mail from yahoo itself and process for delivery (to the next hop which is
located on the other side of the firewall)? How do the resolve the problem?
Thanks.
