About:
Dovecot is an IMAP server whose major goals are security and extreme reliability. It uses index files to optimally store the mailbox state, which makes it very fast even with huge mailboxes. Indexes won't prevent external mailbox updates, so Dovecot is still fully compatible with standard Maildir and mbox formats. There's also a fully featured POP3 server included.

Thank you!
by Apollyon - Dec 5th 2004 18:05:42
I have been using courier-imap for the past 3 years and I must say I have
not been impressed with it. It is difficult to set up out of the box. This
software package took me all of 5 minutes to compile, install and configure
- and it WORKS! I love the extensive variety of configuration options.
Thank you.

Reliability
by Ryan Grove - Jul 28th 2002 21:08:28
Maybe it's just me, but I've always thought of reliability as a major
component of security. If you've got great security but your server
crashes every three days, then what good is the security?

Well, yes, I wouldn't consider a crashy software very secure. Especially
if it crashes randomly. Besides meaning crashes with the "reliability", I
also mean that it functions properly in all cases, even if you have tons
of IMAP clients accessing and modifying the same mailbox, or even in case
of (system) crashes while indexes were just in the middle of being written
to.

Just clarifying: By reliability I especially mean the index files. Often
programs that use binary database files don't allow any kind of problems in
it, or it crashes. If they got corrupted, you have to run some special fsck
to fix it, or even recreate it manually and maybe lose some
information.
Dovecot trusts index files very little. It tries to check every
possible error condition in them, if anything is found the error is logged
and the indexes will be automatically rebuilt. Indexes don't contain any
unique information so rebuilding them won't lose anything.
Also, if Dovecot can't use indexes for any reason (eg. quota full), it
can work without them. Then it just builds the them in memory.

I run Dovecot on a usermode Linux instance with very little memory.
Occasionally the system will run out of memory and kill Dovecot. It seems
to handle this very well. I see error messages in the log about corrupt
indexes, but it keeps on working.

I am assuming you are using procmail to get your e-mail into Maildir/
folders. If so, this is probably where you are getting the corrupt
indexes. If you have $HOME/Maildir/new in your .procmailrc file, change it
to $HOME/Maildir/. The trailing '/' tells procmail to expect a Maildir
format folder. This should eliminate the corrupt index alerts. Basically
with your current configuration you are using MH style messages and not
Maildir. `man procmailrc` for more information.

Email is stored in mbox format, but thanks for the tip.
