If b.com is a virtual alias domain, don't list it in mydestination. Read
ADDRESS_CLASS_README.

A LHS of @a.com will explicitly set up a catch-all alias. If you want
mail to non-existent users in the virtual alias domain to bounce, just
remove that line. For virtual alias domains, don't forget to either list
a.com as a LHS in the virtual alias map, or list a.com in
virtual_alias_domains.

It's a good idea to have fully-qualified addresses on the RHS of virtual
alias maps.
