Fixing 'Relay access denied' in Postfix

  • 772

Before you claim about duplicates and so on, I've checked these topics:

The above topics doesn't solve my problems, perhaps this is something to do with my configuration file which totally differs to one of the topics above, so I'm posting a new fresh topic.

I'm trying to set up Postfix to work with sending emails and mail aliases. If I send an email with my hotmail account to [email protected] I get a reply from hotmail saying:

This is an automatically generated Delivery Status Notification.

Delivery to the following recipients failed.

      [email protected]



Reporting-MTA: dns;blu0-omc4-s15.blu0.hotmail.com
Received-From-MTA: dns;BLU0-SMTP148
Arrival-Date: Thu, 10 Nov 2011 08:31:02 -0800

Final-Recipient: rfc822;[email protected]
Action: failed
Status: 5.7.1
Diagnostic-Code: smtp;554 5.7.1 <[email protected]>: Relay access denied

Subject: Testing

This is a typical test

I already have the mail aliases set up, pointing to the correct emails and such.

This is the /etc/postfix/main.cf I have.

# 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.

myhostname = localhost
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
mydestination = $mydomain, $myhostname, localhost, localhost.localdomain, , localhost
#relayhost = 
relayhost = $mydomain

#mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
mynetworks = 192.168.1.0/24 127.0.0.0/8

mailbox_command = procmail -a "$EXTENSION"
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = all

Here's an log when I sent an email:

    So and where did you specify for which domains Postfix should be responsible? Nowhere. This is why you get this error. Add your domain to the line of mydestination. And then you need at least a local user named developer or put an alias into /etc/aliases.

    But you have to read this documentation as an absolute minimum before you start with Postfix: http://www.postfix.org/BASIC_CONFIGURATION_README.html
