How to find out the classification of a site (and whitelist it) at *other* Symantec customers

I run two sites, http://www.teten.com/ and http://thevirtualhandshake.com/ , and I have found that some employees of large companies cannot view my sites.  I suspect the reason is that the sites are misclassified as 'career' sites, and their employer blocks such sites, probably using software from Symantec and/or other web security vendors.  However, since I don't work at the companies in question, I can't readily find out why I'm being blocked.
 
I would like to find out how you classify my site, and request if necessary a reclassification.  See an example of how McAfee handles this at https://www.trustedsource.org/en/feedback/url?action=checksingle .
 
Does Symantec have an analogous section on its website?  I've tried contacting several names on the Symantec website, without success.

I wrote a blog post on this problem, which is at http://bit.ly/boD9WY .
