It's likely that your MTA (sendmail, or whatever you're using) is doing
this, not mailman.  Try some experiments passing things directly to your
MTA claiming to originate from your virtual host, and see if they get
transformed on the way through.  If not, i'm not sure what to suggest -
i believe numerous people are using the virtual host mailman feature

Re having mailman host multiple lists having the same list name but
different domains, i think thomas fasth's suggestion is a good one - use
separate mailman installs for separate lists.  (You'll have to work out
the MTA details to dispatch to the right mailman install according to
the domain...)

Making a single mailman handle multiple lists with the same apparent
name would take another level of indirection in the mailman code on the
maillist names, plus an option on the mailman pipe command lines.  If
you're interested, this is doable, but definitely not trivial.  I doubt
it will happen until someone directly needing it makes the effort.

It's not an instead kind of thing - it does both.  (At this point it may
be worth "getting your hands dirty" reading a bit of mailman's python
code.  In particular, the docstring for the newlist command gives you
the invocation info; there may be other questions you have that would be
answered in a similar way...)

Clearly virtual hosting is important in the ISP world, and mailman
certainly provides some capability there.  However, we simply *can't*
aim for flawless in any of the myriad dimensions where mailman operates
- mailman has to do a lot of things well, not just any one thing.  It's
at these limits where open source, and a particularly comprehensible
implementation language like python, can be a saving grace.  There are
limits in both directions, of course...
