White listing your email will help it get through a lot of false positive errors big spam blocking services tend to have. Some might think these spam services do this on purpose so you pay for the white list. I’m not saying that. Either way if your email is crucial then it’s worth the small fees to get it through these automated drudges. Here is a current list of the top White list services available now.
- This one is connected to Barracuda a popular stand alone firewall system: http://www.emailreg.org/index.cgi
