You should be able to use the ban_list for this (Privacy options... ->
Subscription rules -> ban_list). The operation of the ban_list has
been improved somewhat since 2.1.5, e.g. In 2.1.5 you couldn't
subscribe a banned address, but you could change your address to a
banned address, but it should work for your purpose.

A regexp like:


will ban every address that is not @domain.ext.
