[Dovecot] Problem moving emails with attachments or HTML links

[J. Wren Hunt]

I recently switched from UW-IMAP to Dovecot (1.0.rc15 on Ubuntu) and am 
experiencing a weird problem that I haven't been able to figure out yet:

If I try to move a message from one IMAP folder to another, all works 
fine if the message is plain text. However, *sometimes* the message will 
not be transferred if it contains either an attachment and/or an HTML 
link (operation times-out). Not all the time, but just enough to be 
annoying. I've looked through the logs and for settings in the .conf 
file and can't find anything obvious that I've overlooked. Can anyone 
help me with any parameters that might be causing this type of problem? 
Thanks so much!
