Linux postfix/dovecot 554 Relay access denied

问题:

I have this error 554 Relay access denied when trying to send email from my outlook client.

I can read incoming mails but cannot send.

If i connect with telnet localhost 25 i can send external emails, but with outlook client it doesn't work.

Here's my postfix and dovecot config :

postconf -n

alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases append_dot_mydomain = no biff = no config_directory = /etc/postfix inet_interfaces = all mailbox_size_limit = 0 mydestination = localhost myhostname = mail.mydomain.com mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 myorigin = /etc/mailname readme_directory = no recipient_delimiter = + relayhost = smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu) smtpd_recipient_restrictions = permit_sasl_authenticated, permit_mynetworks, reject_unauth_destination smtpd_sasl_auth_enable = yes smtpd_sasl_path = private/auth smtpd_sasl_type = dovecot smtpd_tls_auth_only = yes smtpd_tls_cert_file = /etc/ssl/certs/dovecot.pem smtpd_tls_key_file = /etc/ssl/private/dovecot.pem smtpd_use_tls = yes virtual_alias_maps = mysql:/etc/postfix/mysql-virtual-alias-maps.cf virtual_mailbox_domains = mysql:/etc/postfix/mysql-virtual-mailbox-domains.cf virtual_mailbox_maps = mysql:/etc/postfix/mysql-virtual-mailbox-maps.cf virtual_transport = lmtp:unix:private/dovecot-lmtp 

doveconf -n

Any thoughts?

回答1:

If you use a postfix version newer then 2.10, then you need to add the smtpd_relay_restrictions option as described here:

 # With Postfix 2.10 and later, the mail relay policy is # preferably specified under smtpd_relay_restrictions. /etc/postfix/main.cf:     smtpd_relay_restrictions =     permit_mynetworks     permit_sasl_authenticated     reject_unauth_destination  # Older configurations combine relay control and spam control under # smtpd_recipient_restrictions. To use this example with Postfix ≥ # 2.10 specify "smtpd_relay_restrictions=". /etc/postfix/main.cf:     smtpd_recipient_restrictions =     permit_mynetworks     permit_sasl_authenticated     reject_unauth_destination         ...other rules... 

After that, any sasl authenticated user should be able to send mails through the server using smtp.

For my postfix 2.6.6 on Amazon AWS EC2, it turned out that i had wrong configuration of "mydestination" and "relay_domains" settings in main.cf. Correct values (ones which worked for me), were:

mydestination = $myhostname, $mydomain, localhost relay_domains = $mydestination
