[Dovecot] making IMAP quicker on LAN

[Andrew Von Cid]

Hi all,

I keep on hitting this problem when migrating new clients from POP or 
local IMAP servers (hosted on their LAN's) to my Dovecot setup, which is 
hosted properly in a data center.  People usually complain that it's 
slower and although they're getting a kick ass mail setup it doesn't 
look good from their point of view.

I'm wondering if there is anything I could do to speed it up on their 
LAN's.  What I mean is probably a caching IMAP proxy or some sort of 
replication to a local Dovecot server.  Is this something Dovecot can 
do?  I'd be really grateful for any opinions on how to tackle this problem.

Many thanks,


Andrew.
