Just a fun little story.
So I've just finished my contract at my current work but they decided they want to rehire me. So my boss sends off an email to the CEO saying what a great guy I am and what a good server admin I've been.
Of all emails to find a bug/problem on it had to be this one. It appears when the email was sent the connection failed so Outlook scheduled the email to be resent after about a minute. The problem is that Kerio while detecting a problem also thought it was no big deal and sent the email anyway.
In the Kerio Warning log.
[23/Dec/2005 08:21:45] POP3 server connection broken (user from IP): (10060) A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.
Not really a huge deal, however the next time Outlook sent the message the same thing happened, and the next. This happened every minute for 14 hours, 840 times before outlook finally received a message sent confirmation. So the CEO gets in this morning to find 840 emails about what a wonderful server admin I am and how he should rehire me for another year.
Gotta love when things decide to screw up at the worst possible moment.
Well, I hope you still get the job :-)
Anyhow, I don't think the Warning message is the source of the problem, because the POP3 protocol doesn't send the mail, it would be the SMTP protocol.
To prevent this in the future, you can reconfigure Outlook to send mail immediately and not every minute. It can still be configured to receive mail every minute.
