Do you know if that has anything to do with the plugin or is it sth I cannot do anything against? “host mailgate.*.at[80.*] refused to talk to me: 554 Blocked – see” Thanks a lot, Dario May 30, 2015 at 10:37 am #16408 StefanoKeymaster No, it means your web server which is sending the emails is in a black list.
