Hi all! i'm seeing a huge quantity of spam during this week (~156K

from=<0...@carnival.com>
from=<0-gentil...@aditi.com>
from=<0-happy-1...@msf.biglobe.ne.jp>

I tried to reject them by writing a simple rule in my
smtpd_sender_checks by simply appending 0- at the beginning of a new
line but for some reason it isn't matching the pattern, finally
getting rejected by my RBL provider. Anyway I want to avoid doing RBL
checks for this case, any ideas why my rule isn't working? any
suggetions on how to write a filter for this pattern?
Add to your smtpd_sender_checks.regexp file:
/^0-/ REJECT invalid sender address
Should that not be:
/^0\-/ REJECT invalid sender address
Not necessary. The "-" is not special outside character classes.
