After thinking about it, I realize that these problems happen when I move messages from a commercial IMAP email provider (fastmail.fm) to my own, home server (running Dovecot 1.0.rc15 on Ubuntu). In all cases my client of choice is Thunderbird 1.x & 2.x run from an equal mix of Windows, Mac OS/X and Linux platforms.
Well, I've heard this happening with some people, but I've never been able to reproduce it myself. Also I haven't heard of this happening lately.
Do you connect with SSL to Dovecot? By "home server" do you mean it's running in the same computer as your Thunderbird? Or same local network?
Yes, *all* of my IMAP connections use SSL (running on port 993; wrenhunt.com). My local IMAP server is on its own box and separate and different than my clients (Windows and Mac boxes).
Are you able to easily reproduce this? Could you try enabling rawlog (http://dovecot.org/bugreport.html) and check what is the last thing that happens before it hangs?
I've posted the 2 log files here:

These logs reflect me moving 2 emails from one IMAP server (fastmail.fm) to my own box (wrenhunt.com). The first 2 work fine, then the 3rd times out. The client in this case was Thunderbird 1.5.0.9 running on Mac OS X 10.4.8
Thanks for your assistance in debugging this sucker!
