Subject: [PATCH] Deliver mail to <user>@localhost locally using a MDA

Some utilities, such as rkhunter, send mail to root@localhost.
This mail cannot be delivered using esmtp, if there is no
SMTP server running on localhost. With this patch, esmtp delivers
this mail directly using a MDA, just as if it were sent to 'root'
instead of 'root@localhost'.

Resolves: rhbz#1404768
