As an aside, you may want to fix your DNS, as some mail receivers don't
like this:

$ dig -x 72.249.91.101 +short
static.serversandhosting.com.
$ dig a static.serversandhosting.com +short
72.249.3.27

What is really meant to be said is that MTA's which require RFC compliance won't talk to you.  Running an MTA which 
requires minimal RFC compliance (particularly in respect of DNS configuration) eliminates 98% of spam.
