Hello,
I am using two postfix server and quite often some misconfigured mail
server are sending mail to the backup MX instead of the primary.
Both server have postfix implemented using the 'classic' conf:
in main.cf
smtpd_recipient_restrictions =
permit_mynetworks,
permit_sasl_authenticated,
check_recipient_access hash:/usr/local/etc/postfix/access
reject_unauth_destination,
reject_invalid_hostname,
reject_unknown_sender_domain,
# SPF implementation
check_policy_service unix:private/policy
# Greylisting implementation
check_policy_service inet:127.0.0.1:10023
and in master.cf :
# SPF policy implementation /usr/ports/mail/postfix-policyd-spf
policy unix - n n - - spawn
user=nobody argv=/usr/local/sbin/postfix-policyd-spf
The problem is that I sometimes have (quite often in fact) rejected
mail because they are using spf and the mail is transfered from my
backup MX to my master server and my server is considering that second
server as the issuer.
Is there any option that I can activate on master.cf or main.cf to
avoid that… my initial reading and googling have not been very
successful.
Thanks.
