Please excuse the HTML format, it just reads better.

I just gotta say this, 'cause I am thrilled beyond belief with the results
of using Webmin (Virtual Domain + SpamAssassin 2.60-1 + Procmail) & the
Usermin interface for Mail Management. Not using spamc/d yet, and may not.

The long and short of it is, In the last 4-6 weeks I have added SpamAssassin
for myself and brought up a domain (with the same) for end-user Mail
Management.

Today I finally got around to adding TWO SIMPLE RULES to "Procmail" and spam
is now toast. There are of course another million other ways to do it. For
now, this works for me.

Here is a summary of what I am doing.

>Rule #1(UM default setup)
Feed to progam /usr/bin/spamassassin = Always execute action

--LG--
You should really get spamd running.  It is multithreaded and will not only
give better throughput but will handle a larger load.  You may not get a
continuously large flow of mail but the bursts may kill you.
--LG--
  
>Rule #2 (New)
Append to file mail/delete = Match regexp ^X-Spam-Status: Yes,
hits=(5|6|7|8|9)

>Rule #3 (New)
Append to file /dev/null = Match regexp ^X-Spam-Status: Yes,
hits=([1-9][0-9])

--LG--
Instead of [1-9][0-9],

Consider 1?[1-9][0-9]
--LG--

>Rule #4 (UM default setup)
Append to file mail/spam = Match regexp ^X-Spam-Status: Yes

>Before Adding Rules 2 & 3
Setting = Spam message classification options -> Hits above which a message
is considered spam = 2.4

Still managing 200 - 400 emails per day in Spam mailbox. Still
time-consuming.

Getting about 5-10 emails per day in Client Mailbox.

>Since Adding Rules 2 & 3
Delete mailbox has about 2-4 emails per hour.

Spam mailbox has about 1-2 emails per hour. Previously averaged 20-40 per
hour.

Dev/Null -> They're gone to heaven.

False Positives?
Over the last 6 weeks, have gotten these down to less than 1/2 per day. So
feel comfortable w/above setttings, and may move hits 7-9 also to heaven.

Using a score above 10 is usually ok for the base install of SA.  However,
it would be beneficial to start with a higher number like 15 and see if you
get any FPs.  It is better to start high and lower the score over time.
Also if you start to use custom rules, you really should start a score of
>20 in sending to /dev/null.
--LG--

Conclusion
Use Webmin.

Use Usermin.

Use Spamassassin.

Setup a few simple Procmail filters.

Sing daily praises to Jamie and all the other hard-working open-source
contributors.

--LG--
And the choir sang Amen!

And most of all, get back to doing what we do best &/or love.
