Generaly: SMTP Auth using an existing mailbox on an external mail server should always work.

So I setting my gmail:  firstly ssl://smtp.gmail.com:465  and than I try  tls://smtp.gmail.com:587

SMTPAuth user/passwd: my gmail account.

I always get, when I using contact form an error messages: Can't send the messages something went wrong.

Please help.
