Hi,
I am trying to block all mail going to a certain domain. We use
smtpd_recipient_restrictions = check_recipient_access
hash:/etc/postfix/protected_lists
and it counterpart:
smtpd_restriction_classes = list_blocks
list_blocks = check_sender_access
hash:/etc/postfix/list_members,reject
The user@host is not found in list_members.
I added the domain in protected_lists in this form.
$domain.com reject
When sending to his domain, the message bounces with a "Host
or domain name not found"
The domain does not exist but until the code can reviewed and
changed, I have to block these messages.
Any suggestions as to why this does not work?
You've not given enough evidence for anyone to say where the
error is.
Or how do I
configure postfix to not check DNS and simply reject/discard?
I think the easiest way to ban a domain is to add it to the
transport_maps with an entry something like
bad.example.com error:invalid domain
