Hi All,
Sorry if I re-posting again, maybe someone has posted this one before.
I am using postfix and want to certain recipient only receive email
from outside with certain subject. such as t...@mydomain.com only
receive email with subject "test 1" and "test 2"
Is it possible? If yes does anyone has done it ? and how to do that?
Hi marky,
Do you have a spamfilter running? (I have Spamasassin set up, which
could do the trick) You could write a rule (in local.cf) only allowing
very speciffic mails and giving all other mails an exptremely high
SPAM-score resulting in deletion (do try to prevent auto-spam/ham
learning at this point..)
If you are a bit handy with regular expressions, you should get there,
here is something that may help (worte this one down as an example, with
"!", you'll get the "not", haven't tried that one here, but it should work)
# SPAM TEST_1
header __TEST_1_1 From =~ /senderfa...@faultydomain.nl/i
header __TEST_1_2 Subject =~ /A wrong subject/i
body __TEST_1_3 /Stuff in the boddy you do not want to see/i
meta LOCAL_TEST_1 ( __TEST_1_1 || (__TEST_1_2 && __TEST_1_3) )
score LOCAL_TEST_1 99.0
describe LOCAL_TEST_1 LOCAL_TEST_1
for debugging your local filter use "spamassassin --lint"
Best regards,
Eesger
