There is no "for" part in SMTP afaik.
There is a "To" in it. Do you think of this?

This won't work to my knowledge, because if you send out an eMail to 
several "To"-Recipients any mailserver will splitt this message up 
into several ones all cointaining one single line in the 
"Envelope-To".

Example:

	From: blah
	To: abc,123,xyz

will be sent as

	Message 01
	Envelope-From: blah (if not rewritten by the mailserver)
	Envelope-To: abc

	Message 02
	Envelope-From: blah (if not rewritten by the mailserver)
	Envelope-To: 123

	Message 03
	Envelope-From: blah (if not rewritten by the mailserver)
	Envelope-To: xyz

There are other constructions possible like

	From: blah@host
	To: abc@thathost, 123@otherhost, xyz@thathost

These will be sent as

	Message 01
	Envelope-From: blah@host (if not rewritten by the mailserver)
	Envelope-To: abc@thathost, xyz@thathost

	Message 02
	Envelope-From: blah@host (if not rewritten by the mailserver)
	Envelope-To: 123@otherhost

These are only two messages, because mailservers are intelligent 
enough (normally) to see if one message is for different recipients 
maintained by _one_ mailserver (as read though dns lookups).

So, please: What are you trying to target exactly?

bis dahin - kind regards
