Actually, I don't have this problem with Thunderbird either; it became the default mail-client at our Office and one of the reasons behind it was that our average IMAP-archive choked Outlook (and well, so would my inbox, which I archive only yearly and is now certainly over 20.000 messages - so it would bother me). So maybe you're indeed facing the quality of your IMAP client, and it would be interesting if dovecot performs better on an equally sized mailbox (but it does not in our enviroment). Paul P.S. It would be interesting if users want offline mail ;-) that can slow down your client-experience as well. I believe Thunderbird is bad at it but I never really used it. ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
