dovecot - Nov 2007 - Embracing .99

We're stuck on RHEL 4.x, so we're currently working on a plan to live in
harmony with .99 for another year or so. With that said, the plan is
below. Let me know if you have any other recommendations.

[ ]Convert to high-performance mode vice high-security to reduce overall
resource usage.
[ ]Implement iptables throttling for new connections to prevent denials
of service.
[ ]Covert from mbox to maildir to help reduce the likelihood of
corruption that lead to mailbox outages.

As our overall individual mailbox usage is low, maildir seems to be a
good option as mbox corruption has severely impacted a few of our
high-profile applications. However, does anyone know of a sane method to
use maildir on RHEL 4.x without switching over to Postfix?

Thanks!

You are not necessarily stuck with .99. You can upgrade dovecot and you only 
lose support on Dovecot issues. You can use maildir easily with sendmail also, 
as procmail in 4x supports it. You just have to create a procmailrc in /etc 
like below;

MailScanner is like deodorant...
You hope everybody uses it, and
you notice quickly if they don't!!!!

Use Dovecot 1.0x and the default Exim that ships with RHEL4, it all 
works smooth as glass. As mentioned the only thing you lose support for 
is Dovecot, and additionally Exim has great per-user filtering 
capabilities which negate the need to even use procmail.

fwiw,

There are packages for dovecot 1.0.7 for RHEL4 at ATrpms, try them, it
may be less trouble than your current plan:

http://atrpms.net/dist/el4/dovecot/

And no, no RHEL support for non-RHEL shipped binaries of course.
