Send mail for alias addresses

[Infern1]

I recently updated Haraka and found that sending mail for alias isn't working anymore.

Say I login to roundcube via [email protected] and I send a mail for [email protected] it is not working anymore

([7E4999FB-B6E@haraka] Envelope domain 'differentdomain.com' doesn't match AUTH domain 'email.com').

So with some research I found that this is a result of: https://github.com/haraka/Haraka/pull/3265

So I added constrain_sender=false and it is working again.

I understand the function, however can we however make the check not so restrictive?
