Checking header_to has limitations. What if there is more than one
recipient? The above will kill the entire delivery. What if the user
was only cced? What if they were not listed in the header addresses at
all, as will be the case for most of their spam?

A better option is to use an aliasfile, with entries like:


deaduser: :blackhole:

or

deaduser: /dev/null

(these are equivalent)
