Hello List
Since a few weeks i am using postscreen on our mailservers. I really
like the postscreen_dnsbl_* settings as in july they blocked 75% of
spammers.
But now i have a user which fears, that the blacklists could also block
legitim clients because of false positives. So he wants us to let trough
all mails with a RCPT TO: set to his address. He is aware, that he will
then get a lot of spam. But he does not care about that.
In the former setup - without postscreen - i would just have added a
"check_recipient_access" before the "reject_rbl_client" which says
something like
user@domain OK
As far as i have seen this is not possible when using postscreen. The
only solution i could think of is setting "postscreen_dnsbl_sites =" and
"postscreen_dnsbl_action = ignore" and then using reject_rbl_client. But
then i would loose the abilty of having one process blocking the big
masses instead of using a lot of smtpd processes.
So my question is: Am i right or am i doing some reasoning error?
And a little question to Wietse: Would it make sense to also have
settings like the "check_recipient_*" and "check_sender_*" for postscreen?
Thank you for your time and best regards
Matthew
