While investigating my earlier Sendmail confusion I noticed these files:
# ll /var/lib/imap/db/ total 15952 -rw------- 1 cyrus mail 16384 Jan 22 04:02 __db.001 -rw------- 1 cyrus mail 663552 Jan 22 04:02 __db.002 -rw------- 1 cyrus mail 98304 Jan 22 04:02 __db.003 -rw------- 1 cyrus mail 22568960 Jan 22 04:02 __db.004 -rw------- 1 cyrus mail 32768 Jan 22 04:02 __db.005 -rw------- 1 cyrus mail 64 Jan 22 04:02 log.0000000001
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?

Cyrus is a pop3/imap4 server. If you use it, don't touch those files, else rpm -e cyrus-imapd and clean up whatever remains after it.

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.
YMMV
On Fri, May 26, 2006 at 10:55:50AM -0400, William L. Maltby enlightened us:
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...

Didn't really "repoot". Have yet to "poot" the first time this A.M. ;-))
Yes thir! In my prev LFS incarnation I ran my MX in-house. Will end up there someday with this CentOS stuff, but so much to learn and do first.
Thanks for the clarification and taking the time.
Hope you have a bit of time off this weekend.

Like... if I do a yum remove of cyrus-imapd.i386 and cyrus-sasl.i386 it wants to take 205 additional packages with it on the "deep 6" ride. Most are not what I would have guessed had any affiliation. Printre config, KDE stuff, Gnome stuff...
Anyway, I decided that I'd leave those two and just remove the devel and other stuff *very* carefully.
It's hell when you decide to learn this stuff and do a full-blown install so you'll have what you need when you needed it and then can't get rid of what you (think) you don't need when you don't.. well, joking of course.

sasl is what's taking everything with it. SASL is a generic authentication framework that a lot of different apps use, so you'll probably want to leave that one.

Latht potht on thith topic!
A yum provides shows the directory is provided by the two I was going to remove, apparently depended upon by 205 other packages. The __db.004 is
[root@wlmlfs08 db]# file __db.004 __db.004: X11 SNF font data, LSB first
Must be cyrus is contributing more than just a MTA. So I do a
yum provides _db.004
and get
rpm.i386 4.3.3-13_nonptl base Matched from: /var/lib/rpm/__db.004
rpm.i386 4.3.3-11_nonptl installed Matched from: /var/lib/rpm/__db.004
rpm.i386 4.3.3-13_nonptl installed Matched from: /var/lib/rpm/__db.004
Thus far, attempts at longer matches have been fruitless. But it looks like a wicked evil twisted path has been woven here.
