Hi.  I'm hosting a couple domains and email from my home using a consumer high speed cable ISP.  I'm actually routed through Earthlink with Time Warner cable service.


I have a Win7 box running KERIO mail server, APACHE for websites, and FileZilla FTP server.


I'm relaying ALL mail sent from KERIO through my ISP's smart host (because I'm on DHCP ranges blocked by SORBS & Spamhaus policies).


Recently, I noticed that I'm not getting my mail at my work which uses a Sonicwall spam appliance.  So I looked into it and it is marking it as spam for failing SPF.  here's the message from the spam appliance (I changed the server, email, and domain names to protect the innocent!).  What can I do to prevent this from happening?
