Hi All,
First of all I wanted to let you know that I just recently started using
postfix as our
mail server. We've been using sendmail for a long time. I have a
question on RBL
whitelisting. I have done internet search on how to do it but I can't
seem to whitelist
some senders.
Here is a snippet of my main.cf:
smtpd_recipient_restrictions =
permit_mynetworks,
permit_sasl_authenticated,
reject_invalid_hostname,
reject_non_fqdn_hostname,
reject_non_fqdn_sender,
reject_non_fqdn_recipient,
reject_unverified_recipient,
reject_unknown_sender_domain,
reject_unknown_recipient_domain,
check_client_access hash:/etc/postfix/rbl_override,
reject_rbl_client zen.spamhaus.org,
reject_rbl_client bl.spamcop.net,
reject_rbl_client cbl.abuseat.org,
reject_rbl_client dnsbl.sorbs.net,
permit
Here is a sample snippet of rbl_override:
# white listed mail servers
mail.abc.com OK
10.10.10.90 OK
# white listed domain
fred.com OK
# white listed sender
[email protected]
From what I understand, I can only white list mail server's FQDN
or it's IP address.
Is there a way to white list by sender's domain name and sender's
email address.
Some of our client don't have their own mail server so I don't want to
white list the mail server(s) they are using.
Other send us email using their gmail account. Again I don't want to
white list all of gmail's mail server.
I was able to do this on sendmail using /etc/access (hash db) with
the same syntax as above rbl_override example.
Thank you in advance,
