I think someone blacklisted my dns#...

:bang head Every time I try to send an E-mail I get a McAffee poppup stating my E-mail was rejected because my dns# is on a black list at dul.dnsbl.sorbs.net 550 Dynamic IP Addresses.
I'm not a spamzor. I barely send E-mail :eh?: but when I want to, I can't :bang head

Are you trying to send the email out directly? or are you sending to your ISP's SMTP server?

check your ip at dnsstuff (http://www.dnsstuff.com) and see if it's listed in the spam database.

I'm getting three red flags at that site.
I'm sending my e-mails from outlook, I'm using DSL to send, but the e-mail address I'm using is from my dialup account. I've kept the dial up account for back up. Could this be the problem?
