HI Steve,You might want to set up an SPF record (Sender Policy Framework) on your own domain (the orgwideemail address, which is your company domain).When you create an SPF entry against your DNS, you are effectively telling recipients that the named sender (in this case salesforce) is allowed to send mails on behalf of your domain (orgwideemail).Reference: https://salesforce.stackexchange.com/questions/13131/avoid-blacklisting-of-org-wide-email-addressAlso check https://developer.salesforce.com/forums/?id=906F0000000D8enIACHope this helps you.
