According to http://whatismyipaddress.com/blacklist-check my IP is listed with no less than 4 blacklist entities.
My browser was recently prevented from connecting to one of my own client sites (that website's host actually alerted me to this blacklisting), which has since been working, but I have no way of knowing how many other websites might deny access to my IP--or even if my outgoing emails are being denied.
BUT THIS IS NOT AN EMAIL ISSUE. This is a blacklisting issue.
Verizon support via Twitter has been ineffective and pointless:
"Since you have a dynamic IP, we're unable to whitelist your IP at this time. ^JGG"
And Verizon phone support consists of wading through phone menus, waiting 10 minutes to get someone and then listening to them read their script as they fumble around completely and utterly ignorant of what I'm talking about. And then getting disconnected--at least 3 times.
I don't CARE if my IP is "dynamic"; OBVIOUSLY my computer/connection is being IDENTIFIED by an IP that prevented me from visiting that site (and who knows how many others) and, thus, Verizon should be able to erase that from my connection and assign a new [dynamic] one.
All I've gotten so far are excuses, technobabble and stupidity. Anything, that is, but CUSTOMER SERVICE. I pay nearly $100 a month for this **bleep**.
