Easy Mail Delivery with SMTP Smart Host

I knew the downfalls of using the default localhost and the potential mail delivery problems if I didn’t properly set the DomainKey, DKIM, SPF, SenderID, Reverse PTR, and blah blah blah. But it wasn’t really worth the hassle for me to properly set all this, because I can sent the number of emails sent from my server on one hand each day. And a 4 out of 5 times they were administrative emails sent to my Gmail account. But given all that it is still no excuse for poor email hygiene.
