[exim] Retry timeout exceeded - Connection timed out

Hi, my first message to the list.

After searching the web for an answer, I write to the list looking for help.

I have two machines, Exim 4.63.

Message for machine 1 to premio_xatafi@???

2007-03-29 18:55:59 1HWxnW-0003HD-0d == premio_xatafi@???
R=lookuphost T=remote_smtp defer (110): Connection timed out
2007-03-29 18:55:59 1HWxnW-0003HD-0d ** premio_xatafi@???: retry
timeout exceeded

So, message abandoned without retrying.

R=lookuphost T=remote_smtp defer (-53): retry time not reached for any host

So, retries (unsuccesfully, but retries).

May someone tell me why machine 1 have this strange behaviour? And (not
related to Exim), did someone had the same problem with yahoogroups? This
machines process up to 125000 messages a week with no further problem... :(

Thanks in advance for your time.

Regards, and sorry for my English.
