Hello all,
I've setup SpamAssassin to work with individual Vpopmail mailboxes. I want to know if sa-learn can be used in this configuration? If so, how do you tell sa-learn which Bayes database you want to use? I'm currently using one Bayes database per email domain, but I may offer individual Bayes databases per mailbox in the future.
Doug...
I would be interested in how you set SA up with individual vPop boxes. Do you have any notes to share??
Sure, let me ramble for a minute. ;)
First, I should mention that I wanted maximum control over how SpamAssassin works for individual mailboxes. I wanted to be able to turn it on/off individually and configure SpamAssassin settings (ie- Razor, hits, Bayes DB location, etc.) individually for each mailbox and I wanted to store all this in an SQL database for ease of use.
- Obviously you need SpamAssassin installed. :)
I had to make a small change to one of the SpamAssassin scripts because normally it won't read certain settings from a database for security reasons. Notice I have modified the source of SpamAssassin! Please use at your own risk! As long as access to your database is secure, you shouldn't have any problems.
- /usr/lib/perl5/site_perl/5.6.1/Mail/SpamAssassin/Conf.pm
- sub parse_scores_only {
- my ($self) = @_;
- # $self->_parse ($_[1], 1); # don't copy $rules!
- $self->_parse ($_[1], $disallow_rules_in_sql); # allow copying of rules -dougl
- }
- my $disallow_rules_in_sql = 0;
- OPTIONAL: Install Razor. Run 'razor-admin -create' & ' razor-admin -register' as the vpopmail user. This creates a .razor directory in /home/vpopmail. Don't forget to patch Razor if you're using SpamAssassin 2.60 (patch is included with SpamAssasin v2.60).
- Make sure you have a recent version of Procmail installed.
- Create a .procmailrc file and put it in the mailbox directory (ie- /home/vpopmail/domains/<domain>/<user>/.procmailrc
- # Note: paths in this file are relative to the email domain directory.
- # ie- /home/vpopmail/domains/<domain>/
- #
- # The following 4 lines do verbose procmail logging useful for debugging.
- # Comment them out before receiving a lot of email. ;)
- #
- LOGFILE=./pm.log
- LOG="
- "
- VERBOSE=yes
- MAILBOX="./<user>/Maildir/"
- SPAMBOX="./spam/Maildir/"
- USER="<full email address of mailbox>"
- # SpamAssassin filter
- :0fw
- | /usr/bin/spamc -d 127.0.0.1 -u ${USER} -t 3
- :0e
- {
- EXITCODE=$?
- }
- # If you want procmail to put spam messages into another mailbox,
- # uncomment these next lines and be sure that "SPAMBOX" is a valid
- # mailbox
- #
- # Toss Spam into another maildir
- #:0
- #* ^X-Spam-Flag:.YES
- #${SPAMBOX}
- # Deliver the mail to the Maildir
- ${MAILBOX}
- Edit the .qmail-<user> file for the mailbox you want to set up SpamAssassin:
- | preline /usr/bin/procmail -t
./<user>/.procmailrc
- | /home/vpopmail/bin/vdelivermail '' <some email
address>
- Create a MySQL database according to the SpamAssassin docs. Then you can insert records like this:
mysql> select * from userpref;
+-----+--------------------------+---------------------+------------------------------------------------------------------------+----------------+
| oid | username | preference | value | updated |
+-----+--------------------------+---------------------+------------------------------------------------------------------------+----------------+
| 1 | <full email address> | use_bayes | 1 | 20030924164532 |
| 6 | <full email address> | bayes_path | /home/vpopmail/domains/<domain>/.spamassassin/bayes | 20030924164532 |
| 4 | <full email address> | report_safe | 0 | 20030924164532 |
| 7 | <full email address> | auto_whitelist_path | /home/vpopmail/domains/<domain>/.spamassassin/auto-whitelist | 20030924164532 |
| 9 | <full email address> | auto_learn | 1 | 20030924164532 |
| 10 | <full email address> | rewrite_subject | 1 | 20030924164532 |
| 11 | <full email address> | required_hits | 5.0 | 20030924164532 |
| 12 | <full email address> | use_razor2 | 0 | 20030924164532 |
+-----+--------------------------+---------------------+------------------------------------------------------------------------+----------------+
8 rows in set (0.02 sec)
Each user (ie- full email address) can have it's own settings in this table. This makes it really easy to turn on/off every SpamAssassin option on an individual basis.
Note: Currently I'm using one Bayes database per email domain, but I could change that to use one database per mailbox or one database for the entire system right in the SQL table.
These above settings will mark email with the "X-Spam-Flag:" header and you can configure the email client to filter messages unless you un-comment the lines in the .procmailrc file to direct spam messages to a different mailbox.
I think that's most of it. I know this description was unorganized and sketchy, please feel free to ask questions.
