If someone can point me at an explanation of log entries it would be much appreciated.
1) This is a low traffic server. Whenever a new entry arrives for processing, I see what looks like tables getting reloaded, e.g. dict_cidr_open: add a.b.c.0/17 OK dict_cidr_open: add d.e.f.0/24 OK dict_open: cidr:/etc/postfix/ok_client Is that because the subprocesses have exited due to idle timeouts and are restarting? 2) I see what looks like two separate processes stepping on each other during the opening client connection. Is this normal? Is there some setting I can change to alleviate this? All of this traffic is within one second.

[31458]: < localhost[127.0.0.1]: MAIL FROM:<[email protected]> 3) reject_unknown_address: [email protected] rewrite_clnt: cached: local: [email protected] -> [email protected] send attr request = rewrite send attr rule = local send attr address = [email protected] Is the reject_unknown_address an actual rejection, or just something being probed? What does this mean: cached: local: [email protected] -> [email protected] ? 4) rewrite_clnt: local: [email protected] -> [email protected] send attr request = resolve send attr sender = [email protected] send attr address = [email protected] In this case the "sender" above is actually the "to" part of the message, which doesn't seem like a "sender"; and the "address" is the "from" part, which seems like it should be a "receiver". What's the meaning of the above sequence? 5) ctable_locate: install entry key [email protected][email protected] Is this a map insertion with a key of [email protected] for a value of [email protected]? What's ctable? Gary
