5. Configure SendMail to make ProcMail the MailDeliveryAgent^?

• Edit your SendMail config file. Locate the MAILER(local) line near the bottom. Just before that line, insert a new line: FEATURE(local_procmail).

The general theory is that incoming mail will be piped through ProcMail^? and processed according to the "recipes" in each user's setup.

Advantages:

• If you already use ProcMail, then adding SpamAssassin into the mix is pretty easy.

Disadvantages:

• This really doesn't play nicely with SendMailAndCyrus. Sure, you can make it work, but it may be more trouble than it's

6. Return to FilterMailWithSpamAssassin to finish up.

1. Install SpamAssassin

2. Install ProcMail

3. Decide whether to call spamassassin directly, or run it as a daemon

3.1 Calling it directly

Pros:

• Easy to set up
• Unlikely to fail

• Slow when processing many simultaneous requests

3.2 Running as a daemon

Pros:

• Very fast at processing multiple requests
• No startup overhead every time an email is processed

• Use to lose email if the client (spamc) could not contact the daemon (spamd). This is probably fixed.
• A small amount of extra setup is required

To run spamd:

cd /usr/local/etc/rc.d
cp spamd.sh-dist spamd.sh
/usr/local/etc/rc.d/spamd.sh start

4. Make a default ProcMail rcfile with your favorite text editor so that it looks like this:

4.1 Calling spamassassin directly:

4.2 Calling the spamassassin daemon with spamc:

/root# cat /usr/local/etc/procmailrc
DROPPRIVS=yes
:0fw
| spamc

5. Configure SendMail^? to make ProcMail the MailDeliveryAgent^?

6. Enjoy!

• If you have PortInstall^? (from the sysutils/portupgrade port):

  portinstall mail/p5-Mail-SpamAssassin

• Edit your SendMail^? config file. Locate the MAILER(local) line near the bottom. Just before that line, insert a new line: FEATURE(local_procmail).

Enjoy your newly-protected inbox!

X-Spam-Flag: YES

Simply configure your email client to move all emails with that header into their own folder (or delete them entirely, if you're feeling brave), and enjoy your newly-protected inbox!

1. Install SpamAssassin

• If you have PortInstall^?:

  portinstall mail/p5-Mail-SpamAssassin

• Otherwise:

  cd /usr/ports/mail/p5-Mail-SpamAssassin; make install; make clean

2. Install ProcMail

• If you have PortInstall^?:

  portinstall mail/procmail

• Otherwise:

  cd /usr/ports/mail/procmail; make install; make clean

3. Make a default ProcMail rcfile with your favorite text editor so that it looks like this:

/root# cat /usr/local/etc/procmailrc
:0fw
| spamassassin -P

4. Configure SendMail^? to make ProcMail the MailDeliveryAgent^?

• If you haven't already done so, create a LocalSendmailConfiguration.
• Edit your SendMail^? config file. Locate the MAILER(local) line near the bottom. Just before that line, insert a new line: FEATURE(local_procmail).
• Your new configuration file should look something like this:

/root# cd /etc/mail; tail -n 3 host.domain.com.mc
FEATURE(local_procmail)
MAILER(local)
MAILER(smtp)

• Install your new configuration:

/etc/mail# make; make install; make restart
