Postfix Relay Access Denied 554 Error
I have read a lot of posts regarding this error...I have followed the Perfect Setup for FC4 to the best of my ability, but I am having this error with Postfix.
I can use mail perfectly fine on my local network, when I am outside my local network I can receive but not send.
I have checked to enable authentication in my mail client, but it doesn't like the username / password, although I know they are correct because they work for receiving.
If I do the ehlo localhost thing, the output is as expected as described in the Perfect Setup.
220 XXXXXXX ESMTP Postfix
250-AUTH PLAIN LOGIN
This is part of my main.cf:
mydestination = /etc/postfix/local-host-names
smtpd_tls_auth_only = no
smtp_use_tls = yes
smtp_tls_note_starttls_offer = yes
smtpd_use_tls = yes
smtp_tls_session_cache_timeout = 3600s
tls_random_source = dev:/dev/urandom
smtpd_sasl_auth_enable = yes
smtpd_sasl_sasl_security_options = noanonymous
broken_sasl_auth_clients = yes
smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject _unauth_destination
smtpd_tls_key_file = /etc/postfix/ssl/smtpd.key
smtpd_tls_cert_file = /etc/postfix/ssl/smtpd.crt
smtpd_tls_loglevel = 1
smtpd_tls_CAfile = /etc/postfix/ssl/cacert.pem
smtpd_tls_received_header = yes
smtpd_tls_session_cache_timeout = 3600s
Can anyone spot anything here or do I need to give you more info??
Thanks in advance!
