Hi.  I just recently joined this list, like a week or two ago, and
this is my first post.  So, hello.

There's a couple ways around your problem.  First of all, SquirrelMail
is defaulting to sending as <login>@domain because it has not been
told otherwise.  I recently installed the askuserinfo plugin so new
users will be asked to enter their email address.  I have a similar
situation to you, where users' logins are different from their email
addresses.

Another approach is using the genericstable feature of sendmail.  I
assume you are creating the multiple users with the same username
portion of the address using the virtusertable.  For example, if you
had the following entries in virtusertable:

in...@ab...        infoabc
in...@xy...        infoxyz

You could simply reverse this and use it in your genericstable:

infoabc        in...@ab...
infoxyz        in...@xy...

This will cause sendmail to rewrite the outbound sender address.  You
could convert your virtusertable to a genericstable with a simple awk
command.

awk '{print $2"\t"$1}' virtusertable > genericstable

That is assuming of course that you don't have any accounts listed
more than once in virtusertable.  If that were the case, you might
need to resort to something like Perl.  Hmm... I hope I don't get
flamed for that.  Nah, it seems like a pretty civil group here.

There is a third solution, but I believe it requires you to have at
least two separate IPs available.  You run a separate IMAPd on each
IP, and this lets you have the same user id at each domain.  And then
each domain is served on a different IP.  You could have two separate
installations of SquirrelMail, each pointed at the separate IMAPd.  My
friend wrote an explanation of this configuration, based on Cyrus,
which you might find helpful.  http://www.phildev.net/cyrus/

I hope this helps.
