“Why'd it have to be Outlook?”
For the past two weeks or so one of our customers (with a dedicated server)
has been having trouble either sending emails or receiving emails (or both!).
The customer in question uses Microsoft [DELETED-Lookout-DELETED] Outlook (of
course—sigh) so Smirk has been looking into the issue and couldn't for the
life of him get Outlook to work.
Thunderbird? [1]
Yes.
Webmail?
Yes.
Outlook?
Outlook not so good [2].
He spent so much time he decided to reinstall the server (there are some
other issues with the server—namely centered around the control panel
Ravencore [3]) and start over with a fresh slate.
I had just finished installing a new server when P asked if this was the
customer that had the security audit [4].
Oh.
Um.
It is. [5]
XXXX!
I then talked with Smirk to get an exact clarification of the problem and
it's a problem with one (1) email account. Just one. Everything else works
fine. So Smirk left it up to me—if I could fix the original server, fine. Or
if I could get the new server working, fine. Just get it working.
I did some tests on the original server and checked the logs.

Outlook.
Why'd it have to be [DELETED-snakes-DELETED] Outlook?
Needless to say, it worked after making the required configuration change
(and then it was getting it so that the control panel wouldn't wipe out said
configuration change)
