Generally the envelope sender and the mail From: header are independent
from authentication data used to auth against a foreign server, setup as
your smarthost. Both the envelope sender as well the From: header are
typically set by a proper configuration of the mail client. From that
point it can differ between different users.
On the other hand the provider of the MTA which you want to use as
smarthost could have configured his system, so that the SMTP AUTH data
(AuthInfo on your system, user) has to match the address the user tries to
send mail as through that other system. If thats the case, you have not
much luck with Sendmail (Postfix since 2.3 provides Sender-dependent SASL
authentication support; for Exim there are configuration tricks).
