iCloud SMTP as Freemail.hu's outgoing mail server "rejects sender address"
Using verified settings of iCloud's as outgoing server (smtp.me.com, working iCloud username and password, SSL on or off, password authentication, server port 587) as of my freemail.hu (hungarian mail service provider) account on my iPhone 4 iOS5, letters sent from my freemail account arrive in Outbox as Unsent Message with the error message "The sender address ...@freemail.hu was rejected by the server" - with checked working apple server at sending and otherwise perfect iCloud mail account. Any suggestions? Thanks in advance...
