[Dovecot] [OT] Webmail Recommendation

[Hannes Erven]

Hi folks,


I'd like to throw in some real world experience: my IMAP server runs for 
just a few users, but they have huge maildirs (>1GB each) with hundreds 
of folders and, in some folders, thousands of messages.


Before switching to dovecot, courier-imap handled the backend and I used 
Squirrelmail as the front-end.

imapproxy had a huge (positive) impact on performance, especially when 
browsing through folders with many messages. Startup (building the 
maildir tree with message counts) still took its time, and searching in 
Squirrelmail also was a pain.

Thanks to Dovecot, startup and search (in from/to, subject) now is 
really fast and I turned off imapproxy completely as it did not further 
improve the webmail's performance. I guess in environments where 
authentication is expensive (slow) imapproxy sure is worth a look at.


Best regards
