mails sent from [email protected]

hi
first thanks for your amazing work.
the plugin worked and sent correctly but now I see that emails sent through [email protected] instead of my email. I also fill all forms there that with which email have to be send. my SMTP is also correctly filled out and tested, it works. but I think the plugin has something I don’t know.
when the email sent to a gmail address is like : (domain ro a Name I chosed.) and this: [email protected] via -this work normally and from my domain (email.my ex cdomain.com)
just this [email protected] is problem I don’t know from where it comes.

Please help
thanks.
