Subject: [PATCH] send-email: sanitize_address use $foo, not "$foo"
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

There's no reason to explicitly stringify a variable in Perl unless
it's an overloaded object and you want to call overload::StrVal,
otherwise it's just creating a new scalar redundantly.
