Did some research on this with my ISP (very easy to contact them) and it turns out that email from
www.camaro5.com is on a list of not so trustful mail servers. Not every ISP checks those kinds of lists to determine if a particular email should be delivered or not, hence not everyone is affected.
In this case, the check is made in advance of the virus/spam check, so it never enters the system and one has no way of knowing if one came in or not - sans the ISP contact story above. All my emails from this site get trashed daily and it's been that way for some time now.
I just changed my email address here on the forum to a gmail account and I'm hopeful that fixes the issue for me - no emails from this site for many months now.
