While sending mail from one GM Domain to Multiple recipients on another GM domain (local delivery), the following is the example of header (part of it) with only one mail going out instead of multiple copies:
To: demo1@gmdomain, demo2@gmdomain
Content-Type: text/plain; charset="us-ascii"
Delivery-Date: Mon, 05 Apr 2004 09:38:00 +0530
Envelope-To: demo3@gmdomain, demo2@gmdomain, demo1@gmdomain
On Manually running the incoming.pl (which has the Envelope-To included), it is found that the mail is only delivered to demo3@gmdomain and not delivered to others (As in this scenario for local delivery, MTA sends out only one copy of the mail).
What changes are needed so that the mail is delivered to all the accounts, instead of just the first one from the Envelope-To.
