There can be many reason, ranging from the simplest to solve -- courier-imap

running out of some other resource, such as the maximum number of processes
or file descriptors. The first place to look would be syslog.

I honestly cannot see anything in syslog that indicates any sort of
problem is happening.  I've upped MAXDAEMONS and MAXPERIP to values
that are surely not being hit (but even if they were, I'd see an error
in syslog, wouldn't I?).

Yes, you would.

Are there other places I can look? I've checked mail.log, daemon.log, etc.

I can give you more information, such as:

We're using MySQL for the virtual user tables.  Postfix for the MTA.
In authdaemonrc, daemons is set at 5.  I've upped it to 50 before, but
it made no difference.  Even though MAXDAEMONS is set to 500, I rarely
see "ps aux | grep imapd | wc -l" go over 200.

Sounds like everything is working correctly, so you'll have to define with a little bit more detail exactly what you mean by "dropping connections". If you're making this inquiry based solely on an error message from Microsoft Outlook that claims that the connection has been terminated by the server, then kindly go call Microsoft and tell them to fix this well-known bug in their crapware, and stop blaming IMAP servers for their own bug-ridden, virus-spreading mail client crashing internally, but blaming the server for its own bugs.
