Hywel:

If I'm reading you correctly, sendmail doesn't refuse these messages, 
but accepts them, and either doesn't know where to deliver them, or 
attempt to deliver to the "wrong" place if you don't like how the MX 
records are configured for that domain.

This is what I've got in my sendmail.mc:

> FEATURE(`mailertable',`hash -o /etc/mail/mailertable.db')dnl

And this is in my sendmail.cf:

> Kmailertable hash -o /etc/mail/mailertable.db

(If you don't have something like the above line in your sendmail.cf, 
you'll have to regenerate that file.)

If you haven't tried Alex's suggestion yet, it'd be a good idea to run  
"strings mailertable.db" to see what you've currently got in your 
mailertable.db file.
I'm not familiar w/ the wildcard syntax that you appear to be using in 
your mailertable entry.
For testing purposes, I'd suggest explicitly naming each full subdomain 
on the left-hand-side of  your mailertable entry. (w/ no leading ".")

Otherwise, your syntax looks good.
