I'm running a large site email server with qmail1.03 as inbound relay, the
server works with a medium of 600 concurrent inbound connections and relay
they to another host that makes the local delivery.
All time I see the 'qmail-smtpd' and 'qmail-remote' processes to see if all
is working well. qmail-remote mantains in a value of 20 procs. simultaneous,
but in a moment qmail-remote stop tunning, no more qmail-remote processes
was lunched and my queue grow up every second.
I see this error in the /var/log/maillog :
delivery 18323: deferral:
Sorry,_I_wasn't_able_to_establish_an_SMTP_connection._(#4.4.1)
repeated a lot of time.
What can be the problem ?
Tnx.
RDA.-
