Outgoing Mail Server (SMTP)

Host Name : smtp.gmail.com
User Name : "My username"
Password : ************

And in advance part :

I have already tried alternative ways (advices from the Gmail forum )

0/ Tried to create accounts with "Settings - Mail - Gmail" "pop" and then with "Settings - Mail -Others" "Imap"...
Both ways do not work forsending ....but receiving Emails works fine.

1/ I tried alternative Server Port ...... failed
