MailBox Header Control

I'll create a simple Mail Handler that sends e-mail address to a Mailing List.
Problem is that I'm sending the e-mail through the Box and when the Mailing List Program receives the data the it sends the Subscription information back to the box and no the true subscriber.
Can I control the E-mail Header enough to trick the Handler into not thinking it came from... well the box?

just add the "from" in yer header

mail("thelist@mydomain", "subscriber", "list me",
"From: subscribers@email");

Tried it.


I'm using a form and the true sender of the email is the box that processed the email not the email address that the user enters. So the confirmation email is going back to the box and not the user.

how about the "Reply-To: " or "Return-Path: " headers? i would think that one of those would work..

Nope... no go
My host provider says there is no way to control it. They suggest I use an alternative receiving e-mail address and then do batch subscriptions... ?!?

What!?! Doesn't that defeat the purpose of have an auto responding Mail List?
Stupid!

What mail list program?

Cheers,
Keith.

Ezmlm? Not too entirely sure...
