EZMLM and Return-Header

[Andreas Fiedler]

Hi,

I've set up a mailing list with EZMLM. Everything works fine but one thing:
I don't have an entire domain to catch returning (bounced) mail so I need
to rewrite the Return-Path. For example from

[EMAIL PROTECTED]

to

[EMAIL PROTECTED]

Is there any option I can use or do I have to rewrite the Return-Path 
manually?

Thanks for you answers!

Andreas

PS.: It is useles to specify another Return-Path with qmail-inject, because
     EZMLM doesn't use that.
