Hello, Exim 4.72-6 (Debian Squeeze, custom single config file). Mailbox servers handling about 500k mails/day, up to 600 mails/min. Users (including maildir location) are handled with LDAP.
I've seen the above "relaying not permitted" error about two dozen times since these machines started to get more traffic (mailboxes where slowly migrated to them), once I've seen 10 rejects in a second. For addresses that are and were clearly local at the time and in fact worked a few seconds before and after that incident. So the first suspect of course was DNS having a bad hair day and I made sure that all local domains are in /etc/hosts, nsswitch.conf having the proper "files dns" order. Restarted exim after adding everything to /etc/hosts and silence until I got 2 more rejects today. If LDAP were the culprit I'd expect a different (user not found) error so I'm rather stumped and puzzled at this time. Is there any scenario anybody can think of how a relaying not permitted error can occur given the data above? The only thing I can think of is DNS returning an actually flawed/false MX record pointing somewhere not local at the time, any kind of timeout should not be able to cause this error.
