Subject: [PATCH 5/9] Perform correct quoting of recipient names.

From: "Robin H\. Johnson" <[email-masked]>
Date: Wed, 25 Apr 2007 19:37:19 -0700

From: Robin H. Johnson <[email-masked]>

Always perform quoting of the recipient names if they contain periods,
previously only the author's address was treated this way. This stops sendmail
binaries from exploding the name into bad addresses.
