I've been testing Dovecot for a while now and am preparing to replace
our outdated IMAP
system with it. The current system serves about 300 email users who
run a mixture of
clients (Eudora, Apple Mail, Thunderbird and Outlook). Can any of the
many experts on
this list answer a few questions:
1) What's the latest stable release of Dovecot I should be running on this new system
(Dovecot will be running on a RedHat Linux AS 4 64 bit
system with plenty of memory
and CPU). I've been running 1.13 on my test system but I see
that 1.18 just came
out (although I don't know if I should switch to it
immediately.
2) What configuration file options (if any) should I turn on to best handle the range of email clients listed above?
3) Are there any "sizing" options I need to worry about setting for the number of
email users I have (I suspect that 300 users is considered
a rather small
mail system but I want to minimize its resource usage as
much as possible
while still giving decent performance from Dovecot).
And, just out of curiosity, I'm looking into the idea of switching users from mbox format
over to Maildir format on this system (it will use all locally-
connected disks and have no
NFS mounts). Does the Dovecot automatic migration program to migrate
from mbox
to Maildir work well or are there "gotchas"?
Thanks.
