Why is my IP listed as a PBL by spamhaus zen??
Apparently, my Comcast Business IP address is being listed as a PBL by spamhaus since Comcast seems to think it is a residential address or something. How can I get Comcast to not list it as an end-user IP address ranges which should not be delivering unauthenticated SMTP email to any Internet mail server except those provided for specifically by an ISP for that customer's use?
Certainly, Comcast doesn't expect us to use their email system for our business email!
Seriously, what does it take to fix this?

Do you have a static IP? Very often, dynamic IPs are listed in spam blacklists; it is generally recommended to have a static if you want to serve mail. FYI, I have hosted my personal mail on a Comcast business connection for several years now, and have never had my IP blacklisted.

I also would like an answer to this.
Unless I am wrong I thought you could host servers on a comcast business account reguardless of a static IP or Dynamic IP.
Per: http://www.spamhaus.org/faq/section/Spamhaus%20PBL#183
Comcast must have listed these Addresses per a policy that these IP should not be sending mail on port 25.
