If it's just vanilla blacklisting you want, you can do this in Postfix
at the SMTP level and save the hassle of scanning the mail in the first
instance:

To do this, somewhere near the end of your main.cf:
header_checks = regexp:/etc/postfix/header_checks

File /etc/postfix/header_checks looks like this:
/^From:.*whoe...@aol.com/ REJECT sender blacklisted

Postfix reload

Caveat: currently no way to white list anything you add to header checks
- but as you want to blacklist, no big issue there.

Bonus: Can easily and quickly blacklist on any header match (use with
care) not just the 'from'.
