(written as stream-of-conscience as I investigate)
Ok, that is what I thought. I changed it to 1h as a test but things
still seem to not be working. Probably because the following is not
a permanent failure?
2006-12-22 03:17:32 1GxgfO-000JJz-Fi netnews.hinet.net
[168.95.195.16]: Connection reset by peer
(This is just one example I looked up in the logs from a whole ton of
these sitting in my queue)
9h 4.9K 1GxgfO-000JJz-Fi <>
fjphvjlrbsm@???
A lot of them seem to be to hinet.net but also many other "hosts"
Here is another repeating log entry -- someone sending a 451
2006-12-22 02:42:21 1GxgdX-000Ihz-0S SMTP error from remote mail
server after end of data: host grass.kahalacorp.com [64.140.163.121]:
451 Unable to queue message ()
9h 4.5K 1GxgdX-000Ihz-0S <>
ppqcqbakwqc@???
Seems to be ones that just keep rejecting with 4xx errors all the time.
Anyway to automatically detect that and get rid if these anyway :-) ?
Thanks
