I think you might be trying to work it in a more difficult fashion than it
needs to be.

If the user wants "janedoe at domain2.org" to receive mail for
"jane at domain2.org", you only need one local account.  Set up all the
virtual users, for whom "janedoe" is supposed to receive email, to point
at janedoe, i.e.

jane at domain2.org  janedoe
janedeer at domain2.org  janedoe
janedoe2 at domain2.org  janedoe

Then, let the user set up their mail client to send mail as whichever
address they want to reflect as "From:".  That could be "janedoe", or
something completely different.

"jane at domain2.org", "janedoe at domain2.org" and "joanne at domain2.org" can all
point to the same actual user, and that user's login name could be
"joesmith".

The thing to keep in mind is that as long as there are aliases or virtual
addresses, and as long as they can configure their mail client to display
the address they want to use, the username that they use to log in and
retrieve their email doesn't matter.
