There are two ways to fix your virtusertable problem, both are undocumented.
a) Use "!" as RHS for unknown at domain
unknown at domain   !
@domain          unknown at domain
b) define _VIRTUSER_STOP_ONE_LEVEL_RECURSION_ in your *.mc file:
define(`_VIRTUSER_STOP_ONE_LEVEL_RECURSION_',`1')dnl

"a" is "an undocumented implementation detail. "b" is a feature on its way to 
be documented in some future sendmail release. Short description of "b" is 
available in cf/m4/proto.m4 file.

P.S.
Take a look at http://anfi.homeunix.net/sendmail/rtcyrus2.html

You may use the following mailertable entry:
domain	mrs_cyrus_mailertable:local:alias_name
