Fixing 'Relay access denied' in Postfix

Question

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

• Postfix "Relay access denied"
• How to correct Postfix' 'Relay Access Denied'?

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]

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_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:

Solution

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

Thanks for the reply. I added mydomain = domain.com and changed relayhost to relayhost = mail.$mydomain. I get no more error mail from hotmail, but I don't see it in the aliased email inbox. Something wrong?

[mailq]

@YouBook Probably. But without log messages I can't help (new question!). I'm not that good at divination.

[MacMac]

Ah yes, updated my post.

[mailq]

@YouBook Remove the line with relayhost (completely!).

[MacMac]

Updated my post again.

[mailq]

Hotmail doesn't allow to receive mails that were sent by Hotmail. So you should not alias a local user back to Hotmail. This is not the fault of Postfix but prevents spamming. Don't argue with me, discuss this with Microsoft.

[MacMac]

LOL. I guess this solves the problem, just tested using Google mail, works well. Thanks!

I've spent last 6 hours trying to fix this. exact same config layout. Comments were the answer Thank You!
