Trouble with sending mail via Evolution

[Mr geek]

Hi
I`m using Evolution 3.6.3 and set it up for a Gmail account.
But when i want to send new message i give this error:
"
The reported error was "MAIL FROM command failed: Authentication Required. Learn more at
http://support.google.com/mail/bin/a...y?answer=14257 fx5sm2316005wib.11 - gsmtp".
"
What`s the problem?
Thank You.

Check that your gmail account is set to allow POP3 access. Please report back if you're still stuck when you have done that and followed the instructions at gmail's webpage.

i went to Edit -> Preferences -> account editor -> sending mail.
and checked "Server requires authentication" check box!
