Hi Everyone!
I would like to use reject_unlisted_sender to allow only one From: address
to be used to send email from my mail server. But it is not working, it
seems to still just be allowing all From: addresses. Here is the output of
what happened:
main.cf
myhostname = xxx.yyy.com
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
mydestination = localhost, yyy.com
relayhost =
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = loopback-only
smtpd_sender_restrictions = check_sender_access
hash:/etc/postfix/listed_senders reject_unlisted_sender
--- I added the last line, the rest of the config is the same as we
did it a few years ago.
--- I created the file /etc/postfix/listed_senders
listed_senders (contents of file)
notificati...@yyy.com OK
--- I issued:
postmap hash:/etc/postfix/listed_senders
--- listed_senders.db has been created
--- But it is not working, postmap still delivers email for any From:
address
