I have setup Postfix and Dovecot on my CentOS Server.
Now I am using unsecure SMTP and POP/IMAP (ports 25 and 110/143). I can send mail locally to and from myself, but when I want to send email TO my gmail account, eg. firstname.lastname@example.org, it responds:
Relay access denied
I tried the following, but it still gives me an access deny issue. Made the following changes to
smtpd_sasl_local_domain = smtpd_sasl_auth_enable = yes smtpd_sasl_type = cyrus smtpd_sasl_security_options = noanonymous broken_sasl_auth_clients = yes smtpd_sasl_authenticated_header = yes smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination
