When adding a "From email and send copy"-field, it is recomended to only
populate th e "Reply-to" field due to SPF and spam-filters. But when I select
that it should only populate the "Reply-to" field and at the same time selects
that the sender always should get a copy, the copy is sent woth a blank email as
the sender. This is also something the spam-filters can stop.

As a solution there should be an "From email" option in the same way as in the
"Send to specific email-adrsses"-field. Or it could just use the global sender
name specified in CMS Mailer.
