Thanks Aaron for your reply
Well, my CFLAGS are
CFLAGS="-O3 -march=pentium3 -fomit-frame-pointer"
CHOST="i686-pc-linux-gnu"
CXXFLAGS="${CFLAGS}"
And these are replicated for all my machines. Only change maybe was going
from a generic flag for pentiums to this standard...
How does one use the sunrise builds?

2.2

Hello,
My current DBMail system is getting very unstable and needs a full
reset every now and then with the system complianting about not having
enough database connections or imap connections that fail after a few
seconds. (Currently usinbg 2.0.10 on Gentoo Linux with postfix/mysql)
Also, my nightly cleanup database script is currently running for 55
minutes at midnight and no one is able to check their mail during that
time of day. For some reference, I have about 60 real users and my
Database size is about 2 to 4GB runing on a Pentium-III 1Ghz with 1GB
RAM.
The hardware you have should be plenty to handle those database sizes
under reasonable usage levels, so something is definitely gone wrong
with your installation. Have you ever used complex CFLAGS at any time?
Misusing the ability to provide absurd CFLAGS is the Gentoo user's kiss
of death, and it is the first thing I would look at before looking at
any specific problems.
The base OS is patched for a few years, I am going to do a fuull
reimage and reinstallation. And hopefully most of these problems would
be gone.
My first question would be what would be the best method to do the
install, download the .tar.gz, follow the normal method or use
portage? (I am aware that dbmail is not in the main portage database,
but if I am going to use the ebuilt, what are the commands/step I
should be taking?) And which init script files should I be using. (I
was using the posted Gentoo ones from the mailing list a few years
ago)
Use the Sunrise ebuilds, they work well. If you want to use libSieve, it
is in the main Portage tree.
Second question is is 2.2 stable enough? I don't want a confidence
lost with my users when I perform the upgrade. I am very interested in
the LDAP as I want to implement a groupware package during this round
of upgrades.
2.2 is very stable, much more than 2.0. You'll like it!
My Third question is, it is possible to use a second machine to do
anti-spam filtering? I am considering doing this as it gives some
redundancy to my mail setup as I can set the primary reciever to this
machine and it forwards to the real mail server. (As well as keeping
the email server nice and simple) Any community views on this?
Yes, and this works fine generally by using SMTP to move mail from the
anti-spam host over to the main mail server. There are several howto
guides on the DBMail wiki, and many, many more guides on anti-spam mail
relays out there, just search a little and you'll find 'em.
