Feat: Don't append tag if the provider doesn't support `+` addressing #254

Many email providers like yahoo.com don't support plus addressing. So mail to email+tag@example.com that is redirected to user+tag@yahoo.com will bounce. As a fix, we can redirect email+tag@example.com to user@yahoo.com

Can be implemented by appending a minus (-) to the domain, like forward-email=user@-rocketmail.com. As per RFC952, the first or last character cannot be -:

The first character must be an alpha character. The last character must not be a minus sign or period.
