When I telnet to my server thats running postfix and try to send an email:
MAIL FROM:<
[email protected]>
#=> 250 2.1.0 Ok
RCPT TO:<
[email protected]>
#=> 554 5.7.1 <
[email protected]>: Relay access denied
I couldn't really find the answer on the site or by looking at other users question/answers, I'm not sure where to
start. Ideas?
Update
So basically looking at the docs: http://www.postfix.org/SMTPD_ACCESS_README.html (section: Getting selective with SMTP access restriction lists), I don't seem to have any of those directives in etc/postfix/main.cf
like smtpd_client_restrictions = permit_mynetworks, reject or any of the other ones, so I'm quite confused.
But really I'm going to have a rails app connect to the server and send the emails, so I'm not sure how to handle it.
Here is what my config file looks like:
# 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 = rerecipe-utils
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = /etc/mailname
mydestination = $myhostname, localhost.$mydomain, localhost, mail.rerecipe.com, rerecipe.com
relayhost =
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = all
inet_protocols = all
mynetworks = 127.0.0.0/8 204.232.207.0/24 10.177.64.0/19 [::1]/128 [fe80::%eth0]/64 [fe80::%eth1]/64
Something to note is that relayhost is blank, this is the default configuration file that was created when I installed Postfix, when testing to connect with openssl I get this:
~% openssl s_client -connect mail.myhostname.com:25 -starttls smtp
CONNECTED(00000003)

Oddly enough when I try to send an email from the machine itself it does work:
echo test | mail -s "test subject"
[email protected]
