is rumored to have said:
Hi,
I keep getting disabled on [email protected] mailing list. I
have resubscribed many times. Is there a problem with my
configuration? What can I do to fix this?
You need to stop rejecting mail from the list. That could be because
you've chose strict DMARC enforcement, which is incompatible with most
discussion mailing lists.
I am not using DMARC.
I am using:
smtpd_recipient_restrictions =
permit_mynetworks,
check_client_access cidr:/usr/local/etc/postfix/client_checks,
check_sender_access hash:/usr/local/etc/postfix/sender_checks,
check_sender_access hash:/usr/local/etc/postfix/sender_access,
reject_unknown_sender_domain,
reject_unknown_reverse_client_hostname,
reject_unknown_client_hostname,
reject_invalid_helo_hostname,
reject_non_fqdn_helo_hostname,
reject_non_fqdn_hostname,
reject_non_fqdn_sender,
reject_non_fqdn_recipient,
reject_unknown_helo_hostname,
reject_unknown_reverse_client_hostname,
reject_unknown_client_hostname,
reject_unauth_pipelining,
reject_invalid_hostname,
reject_unauth_destination,
reject_unknown_sender_domain,
reject_unknown_recipient_domain,
reject_rbl_client zen.spamhaus.org,
reject_rbl_client psbl.surriel.com,
permit
Can I add something to make sure that postfix.org emails are not
rejected?
OR: If you are forwarding the messages from the list to anywhere that
has strict DMARC enforcement: STOP DOING THAT.
I don't forward any of my own emails anywhere, I really like to use pine
email client on the server myself, but this is not for everyone. What is
funny is everyone asked for webmail, but now that I have it working,
everyone wants theirs forwarded. I think I am the only one using
roundcube.
Kind Regards,
Al
