I have 2 simple and similar emails that are getting blocked intermittently (maybe one out of 10) by HotMail, Comcast and occasionally RoadRunner. However, AOL, Yahoo, GMail, SBCGlobal, etc. are rarely a problem. These emails do pass Barracuda, Spam Assassin, Bright Mail, IronPort, Cloudmark and MessageLabs. They both fail Postini. Occasionally these emails aren’t bounced but arrive in the spam box. I will provide [url removed, login to view] only 1 or 2 emails to all of the above nearly always arrive properly.
