[PATCH 6/9] Validate @recipients before using it for sendmail and Net::SMTP.

["Robin H\. Johnson" <robbat2@gentoo.org>]

From: Robin H. Johnson <robbat2@gentoo.org>

Ensure that @recipients is only raw addresses when it is handed to the sendmail
binary OR Net::SMTP, otherwise BCC cases might get an extra <, or wierd stuff
might be passed to the exec.
