OK. This doesn't look like a server rejecting the mail. It would appear to be a connection problem. Can you confirm a couple of things:
1. Can you check in the mail log that you can see a connection
from your BBNET machine that corresponds to the start of
a period that BB reports the machine down. I wouldn't rely
too heavily on the timestamps here unless the machines are
perfectly synchronized. Just follow the BBNET connections
in the log and see if there is a gap.
2. Can you also give us some idea of the type of hardware thatIt is "the internet", simply. Is is two different colocation centers with very different upstream providers.
connects the subnets which are being traversed. There are
some things that will handle TCP and ICMP differently. It's
possible that "ping" is always accepted and "smtp"
occasionally blocked.
3. Are you testing anything on the mail servers other thanYes, on smtpmachine ssh is tested as well. It also has regular problems, but not that much. With smtp they occur every 20 to 120 minutes, with ssh every few days. And the ssh service does not get a red "down" dot, but a black "unavailable".
"conn" and "smtp"? If so, do these test also report
problems?
