Attached is what I use, found it on a webpage about installing SA when I
was going through it. Customized slightly for my local usernames and ways
of doing things.
When spamd dies, all mail continues to come through, it just doesn't get
analyzed by SA until spamd gets restarted.
Here's my config bits:
Postfix:
master.cf:
smtp inet n - n - - smtpd
-o content_filter=spamchk:dummy
spamchk unix - n n - 20 pipe
flags=Rq user=spamfilter argv=/usr/local/bin/spamchk -f ${sender}
-- ${recipient}
attached files:
spamchk - the filter script that gets called, pushes messages over to
spamc... note I commented out the bottom half of the script snice I don't
use that functionality currently, but may on other boxes in the future so
I left it there for reference.
spamdcheck.sh - wrote this scruipt to run every 5 minutes to check to see
if spamd is running. I've had instances where spamd just dies in the
middle of the night, but leaves the pidfile there, so I wrote this to
check and restart... might be crude, if anyone has suggestions on
bettering it, please do (also it monitors the number of spamd children to
tell me if I need to adjust child parameters if I'm running too many
processes).
Any questions, let me know.

Any other thoughts?
I just found this:

mfg zmi
I have already tried this script and it was very close to what I was wanting,
but it does not connect to spamd in any manner. It actually uses the perl
libraries to interact with spamassassin in it's own manner, plus it is not
designed to use per user preferences/bayes/awl.
Thanks anyway Michael.

# Run the check to see if spamd is running by running a ps and checking the
number of #

that #

at #

restart #

let them #
