Hey Ryan.

A couple things you can do.

Experiment with "check this account when sending / receiving" - this seemed
to result in multiple connection streams...

The other answer you already found... Outlook - depending on version - can
have 2 - 4 sessions active per account... with exchange and other IMAP
servers like uw, the new connection from the same IP terminates the original
connection I think - but with courier, it can have multiple connection tied
up at once for EACH account.

Your auth daemons should be fine with 5 though - I have hundreds of active
accounts on some of my servers and never had to increase the number of
authdaemons.

The problem gets worse when you NAT - I've got clients with 20 mail boxes
using outlook, so my max per ip is around 100, which makes it real easy to
DOS the IMAP service - defeating the purpose of the setting... but whatcha
gonna do?

20 mail boxes, 4 connections, plus a few who have multiple mail boxes...
adds up to 100 sessions peak at once pretty quick.

Ok, I increased the number of connection from one IP from 4 to 10 in the
imapd config file, and the number of daemons from 5 to 10 in the
authdaemonrc config file.  Everything seems to be working fine now.

Seems to need more connections with the more folders I have expanded.  I am
checking 3 different e-mail accounts at once, so that would account for a
need for more connections.

But my question is, is this recommended procedure?  Are there any other
ways?  Any repercussions because of this?

Thanks.

I had this happening too, only it was from Mail.app on OSX.  Turns out
that it was trying to authenticate a bunch of times in rapid succession,
turning up my daemons="#" to 40 (we have several mac users) in
authdaemonrc fixed it.  May not be your problem, but it can't hurt to try.
