I've posted this a few times before.
Blocking emails based on the Subject line can be done by adding the
following LOCAL_RULESET to your sendmail.mc file, and then rebuilding
sendmail.cf. PLEASE NOTE that there are TABS in the code below. If you
copy/paste the code below into yout sendmail.mc file, BE SURE TO REPLACE any
occurances of "[TAB]" with a real TAB.
Once the sendmail.cf has been rebuilt (and sendmail restarted), create two
files. The first file (subjects_full) will contain COMPLETE SUBJECT LINES,
using PERIODS to replace any spaces. The second file can contain any
KEYWORDS or portions of subject lines (again, replacing any spaces with
periods).
For example, in /etc/mail/subjects_full you might have something like:
Mothers.Day.Order.Confirmation
Dangerous.Virus.Warning
Virus.ALERT!!!
Important!.Read.carefully!!
How.to.protect.yourself.from.the.IL0VEY0U.bug!
I.Cant.Believe.This!!!

Hi,.how.are.you?
In /etc/mail/subjects_part you could have something like:
unsecured.gold.mastercard
unsecured.mastercard
unsecured.platinum.card
unsecured.visa
viagra
v.i.a.g.r.a
vi*agra
v1agra
v*1a*gra
These are plain ascii files... NOT database hashes. And, there is no need
to restart sendmail whenever you add anything to these files. Changes take
effect immediately.
Have fun!
LOCAL_RULESETS
######################################################################
###
### Email Virus and Anti-SPAM stuff...
###
### Add exact-match subject lines to /etc/mail/subjects_full
### Add substrings to match in subject lines to /etc/mail/subjects_part
### In both files, all spaces MUST be replaced with periods (.)
###
### Create two files called /etc/mail/subjects_full and
### /etc/mail/subjects_part. The former has complete
### unwanted 'subject' lines, while the latter has only
### substrings within 'subject' lines.
###
### As an example, suppose you want to filter out 'viagra'
### spam. The following entry in your subjects_part
### file would do it:
### viagra
###
### In the case of multi-word entries, all spaces MUST be
### replaced with periods. For example:
### herbal.viagra
###
### These filters are not case-sensitive.
