SMTP problem

[dkwok]

Just lately I can see a lot of smtp error from the maillog.   Jun 27 15:04:18 rat qmail: 993618258.266703 end msg 201631 Jun 27 15:07:15 rat qmail: 993618435.241489 starting delivery 9199: msg 201646 to remote [EMAIL PROTECTED] Jun 27 15:07:15 rat qmail: 993618435.243444 status: local 0/10 remote 1/20 Jun 27 15:07:16 rat qmail: 993618436.669417 delivery 9199: deferral: Sorry,_I_wasn't_able_to_establish_an_SMTP_connection._(#4.4.1)/ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^   Jun 27 15:07:16 rat qmail: 993618436.670346 status: local 0/10 remote 0/20 Jun 27 15:07:23 rat qmail: 993618443.686308 starting delivery 9200: msg 201612 to remote [EMAIL PROTECTED] Jun 27 15:07:23 rat qmail: 993618443.688209 status: local 0/10 remote 1/20 Jun 27 15:07:24 rat qmail: 993618444.723975 delivery 9200: deferral: Sorry,_I_couldn't_find_any_host_by_that_name._(#4.1.2)/ Jun 27 15:07:24 rat qmail: 993618444.724894 status: local 0/10 remote 0/20   I have telneted port 25 by hand and the connection is ok. This was done to eliminate the possibility of blocking by my firewall. However, it doesn't seem to be the case.   Any suggestion?   David Kwok
