    I'm using Postfix with Dovecot, I have problem with sending mails to outside networks, there is no problem with internal network. I can receive mails from any external networks. I'm not sure what I have done wrong.

    mail.log
    Code:

    Did you restart Postfix?

    Is this all in one line?
    Code:
    smtpd_recipient_restrictions = permit_sasl_authenticated,
    permit_mynetworks, check_sender_access hash:/etc/postfix/mails,
    reject_unauth_destination
    If you use multiple lines for this statemant, please make sure that from the second line on, the lines begin with at least one emtpy space.
