I have never used milter-regex, but none of these regex should ever
match "mail16.websecurestores.com".
The manual page for milter regex states the following:
When resolution fails, the hostname contains the numerical address
in square brackets.
in case your resolver fails to resolve 209.147.117.6 ->
mail16.websecurestores.com,
/[0-9][0-9]*\.[0-9][0-9]*\.[0-9][0-9]*/ will successfully match
"209.147.117.6"
