The Mailer class has the method cleanHeaders()
Which calls for the headers 'To', 'From', 'Cc', 'Bcc' the method cleanAddress()
I like to add a Reply-To header with $this->setHeader('Reply-To', $address, false), but that is not cleaned this way.
- can Reply-To be added to this list of cleaned adresses?
- I think it is useful to consider adding the Sender header to this list as well.
- (Note: some PHPDocs refers to setAddress(), but that method doesn't exist (any more))
