First, change them to one line as Martijn suggested: /^From: .*boarding.*\@domain\.com$/ REJECT junk Note the $ at the end of the match, that is quite important. then postmap -q "boarding(a)doamin.com" regexp:/etc/postfix/headerchecks Also, be sure and test anything like this very carefully. You might even consider running it with a WARN instead of REJECT for a time. I would recommend that instead of 'junk' you have a longer description, even if it is only "Boarding Junk", but "Suspicious user name BOARDING not allowed" is probably better. -- Instant karma's going to get you! |
