SPF records will help! Also called Sender ID, this is a straight forward DNS implementation to help prevent Group Email from being rejected or listed as SPAM. Below, I will detail the steps for implementing...
Recently we've been getting the following errors from livemail [hotmail] email recipients:

So, this helpded me remember I setup an SPF record a long time ago [2005], but never added fellowshiponemail1.com domain or it's originating IP address as a valid place IRVINGBIBLE.org emails could come from.
To start, you can check what your current [if any] SPF records indicate by sending a test email to check-auth@verifier.port25.com
There's also a SPF record creation wizard at http://www.microsoft.com/mscorp/safety/content/technologies/senderid/wizard/default.aspx
At step 3 under the heading:
Outbound Mail Server Addresses
enter the following domain and IP information in addition to your normal outgoing mail server information:
208.36.200.224 /27
fellowshiponemail1.com
Our final updated SPF record for our DNS provider looks like this:
v=spf1 ip4:216.215.65.5 ptr:ibcmail.irvingbible.org ip4:208.36.200.224/27 a:fellowshiponemail1.com -all
Hope this helps!
