Any clues ?
Yes, your MTAs seem to have a problem writing to
mail.server.co.uk, which is why the connection gets a timeout
after some time.
Which is astonishing, as there is no SMTP server listening on
that host, so there should be a temporary error - but not the
one you are getting.
Well, maybe they had a problem with mail.server.co.uk and are
fixing the problem at the moment.
Hi
Sorry, I used mail.server.co.uk as an example, it is happening on approx 10
or so servers.
There are many possibilities here, and obfuscating the remote mail
server doesn't help reduce the list of possibilities...
if you can send to these servers, but only get the timeout few times,
then they are overloaded so your server will need to retry later.
if you can never send to these servers, they may be blocking you (this
could happen if they believe that you are in residential block).
PS. There is a dns mismatch on one of your mail servers:
# host 66.98.180.26
26.180.98.66.in-addr.arpa domain name pointer mail.deniscroombs.org.
# host mail.deniscroombs.org
mail.deniscroombs.org has address 209.139.208.133
