Niedawno skonfigurowałem serwer pocztowy na linode przy użyciu Postfix, Dovecot i MySQL. Mogę wysyłać i odbierać wiadomości e-mail z klienta pocztowego (Outlook), ale za każdym razem, gdy próbuję wysłać pocztę z użytkownikiem z witryny Wordpress, zaprojektowałem to nie działa. Oto dane wyjściowe z dziennika błędów:
