The main question is your intended mail folder format -  mbox or maildir?

Each have various tradeoffs (mbox better for huge numbers of read-only 
msgs, maildir better for huge but actively changing folders).  Dovecot 
doesn't (afaict) conveniently support mixed folder format (except for 
the special case of INBOX).

I personally run with several Gb of Maildir, with folders of 20k+ 
messages (my spam folder :<) and Dovecot has
never been a problem..... pity I can't say the same about Thunderbird :<
