I increased the prefork value from 5 to 50 (in slow increments) and it appears to be able to download more headers but still drops the connection. The version of Mail.app that I used was earlier version and up to the latest, 1.3.9 (v619).
I have had a similar problem with one user that uses Ximian Evolution 1.4.6. Same error message on the server side, on the client side, says something to the effect of "connection unexpectedly dropped". I know this is probably related to bad IMAP programming on the client side, but since most of my users (including my boss) use Mail.app to read mail I want to make sure this is going to continue to work for everyone as the spam levels and sizes of INBOXes rise. What puzzles me even more is that MacOS X Server 10.3 uses Cyrus-IMAP, and I found some of the settings to make Cyrus work better with Mail.app in configuration files on my XServe, but my real mail server is actually on a Red Hat Enterprise 3 box.
I would greatly appreciate any help you could provide on this matter.
