So, right now I am halfway through trying to setup an outgoing-mail blacklist, by way of smtpd_recipient_restrictions
.
The problem I am experiencing is that my test emails are being delivered when I am expecting them to be rejected by the system.
Here's the /etc/postfix/main.cf
# See /usr/share/postfix/main.cf.dist for a commented, more complete version
# Debian specific: Specifying a file name will cause the first
# line of that file to be used as the name. The Debian default
# is /etc/mailname.
#myorigin = /etc/mailname
smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
biff = no
# appending .domain is the MUA's job.
append_dot_mydomain = no
# Uncomment the next line to generate "delayed mail" warnings
#delay_warning_time = 4h
readme_directory = no
# TLS parameters
smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem
smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key
smtpd_use_tls=yes
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache
# See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for
# information on enabling SSL in the smtp client.
smtpd_recipient_restrictions =
reject_unknown_recipient_domain,
reject_unauth_destination,
check_recipient_access hash:/etc/postfix/recipient_block
myhostname = hostname.domain.com
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = /etc/mailname
mydestination = hostname.domain.com, hostname.domain.com, , localhost
relayhost =
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
mailbox_command = procmail -a "$EXTENSION"
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = all
My /etc/postfix/recipient_block
(this was run through postmap afterwards)
personalemail@anotheroneofmydomains.com REJECT
And then, I'm sending the test email like so:
$ echo test | mail -s "test email, please ignore" personalemail@anotheroneofmydomains.com
Postfix has had its conf reloaded, has been restarted a couple times to try and troubleshoot, all to no avail.
A chunk from tailing the /var/log/mail.log
file reads like so:
Sep 25 02:27:17 antares postfix/master[3024]: reload -- version 2.7.0, configuration /etc/postfix

Sep 25 02:27:28 antares postfix/qmgr[3105]: C723018770: removed
...So, I'm stumped. I don't see why the email isn't being rejected.
