Re: [gentoo-user] postfix error: External senders are prohibited to send to local recipient

Thank you for the input.
Yes, you are correct, in my case "postfix" was missing "sasl" flag.
I needed to run:
postmap hash:/etc/postfix/saslpass

and add entry to:
/etc/postfix/sender_canonical

now it works; until Rogers decided to add something new.
