I would, probably, use special perl (or python, or whatever is your
favourite) script emulating the 'smtpserver-router protocol', and run
that under the smtpservers.

Snafu there being: the way to start the router process is hardcoded.
Hmm.. At least the options are.   The  smtpserver  program has '-R'
option that can be used to set, what router binary to use for these
verification tasks.
