While investigating my earlier Sendmail confusion I noticed these files:

The date/time stamps suggest that these files were create by a cron job the day after I installed CentOS v4.2 and have not been modified since.
I haven't done any explicit Cyrus configuration, and actually I don't have a clear idea of what mail-related functionality Cyrus actually provides. If it is in use at all on my system it is done as some aspect of the default CentOS4 installation. Those __db files are not owned by any RPM package, although the /var/lib/imap/db/ is owned by the cyrus-imapd package.
Do I really need a 22MB empty database file on my system?
I've got 'em too! And I just do evolution/thunderbird pop3 only. Must be needed... until we discover them. Thanks, I had not! :-)
I'm gonna move the directory away and see what happens.
<snip sig stuff>
Well, moved the directory, repooted and both evolution and thunderbird continue to work in and out. But, I *don't* use imap, only pop-3. I have sendmail disabled. My server incoming is ISP's pop server and outbount is my ISP's SMTP server.
Cyrus is used to *serve* POP3/IMAP from your machine. If you aren't checking mail that is delivered to your box, you're not using it and can most likely get rid of it.
If you're running a mail server, then it's usually useful to get the mail back off, in which case you could use Cyrus, Dovecot, or any number of other POP3/IMAP servers.
Hope that clarifies...
