Before upgrade (Plesk 10.x) the main.cf for postfix (/etc/postfix) has the directive "inet_protocols = ipv4". This has been set because of some german mail providers and google.
After upgrade (Plesk 11) the main.cf is changed to "inet_protocols = all", which instantly creates problems with several mail providers.
Please check and fix for future releases.
Kind regards
