Problem sending to Comcast email

Question

I am having a problem sending an email to anyone who is using comcast.net email. 
This is something that just started about 3 weeks ago.
I have a web site, if I send an email with the web site listed anywhere in the email, www.beaumontfamilyhistory.com,
the comcast server dumb's the email into the spam folder on their server, the email is not downloaded to anyone's computer.
In order to find it the person has to sign in to there comcast mail account and retrieve the email out of the spam folder, even after saying its not spam
and I send them another email it goes into the spam folder.
If I send the same email with out the web site link the email goes through just fine. 
It has been over a year that I have had the web site listed on every email I send out, the problem has been just
in the last couple of weeks.  I have checked the web site with spam criminal, and other sites and all have indicated its ok.
The site is hosted at Host Excellent, its only a web site with no email, of course Host Excellent says there is not problem
on there end.  Comcast says they are not blocking my email,
Anyone have any suggestions, greatly appreciated
