hello, I am using RCU and courier-imap server with 30000 emails folders and not possible to use (more than a minute to see email list). Change server to dovecot will help in speed terms?
Short answer: yes.
Longer answer: yes, in most cases dramatically (it sure did for us).
Longest answer: yes, and in most cases dramatically, but you should do a little legwork to decide on configuration choices - ie, what mail storage you will use, what filesystem said storage will reside on (might depend on the answer to the first question), etc...
Do I need to change something in user boxes?
Depends...
You would be much better off asking this on the dovecot list.
