Are you using a SASL mech that supports proxy auth?  The imtest manpage 
says:

        -u userid
               Userid  to  use  for authorization; defaults to the current 
user.  This is the userid whose identity will be assumed
               after authentication.  NOTE: This is only used with SASL 
mechanisms that allow proxying (e.g. PLAIN, DIGEST-MD5).
