Thanks for the answer, I did not try to use TLS. At home, could connect using the scmddm user name (without the dot symbol and without part @ <...>), user ftp = user site: scmddm - true sc.mddm - false sc.mddm @ <...> - false scmddm @ <...> - false and I need to use the option: Use passive transfer mode After tomorrow I'll try again at work, maybe I banned the server while I tried to connect using the full email.
