Field Envelope-From

How can I specify the sender’s address (MAIL FROM)? In this case, the login is equal to the Envelope-From, but MAIL FROM – is other.

You can do it by going to settings after configure your smtp service, but It’s really depends which smtp service use.
For example gmail allow to use from just after you setup and validate the email from the web interface.

I would contact the smtp service and check if you can do it.

How to do it:
Login = [email protected]
Password = ****
Protocol = SMTP
Security = STARTTLS
Mail-from = [email protected]
Envelope-From = [email protected]
