The envelope sender doesn't have to match the From: header, as From: may
contain multiple addresses. If so, Sender: should exist and contain only
one address.

Yes, I'd consider this as a misconfiguration of the webmailer.
Most people do not care, because the do not know anything about envelope
senders. The same is true for MUAs. And for replies normal MUAs use the
From: header (or Reply-to:, if available).
The envelope sender is used for bounces. And even webmail users should
get the bounces they triggger. But with having www@??? as
envelope sender, there is no chance.
So - you should try hard to set the envelope sender to the address of
the "responsive" originating user.

The variables you need are
$sender_address
$sender_address_local_part
$sender_address_domain

How to you test your setup?
