Any computer wizards?

I've noticed some weirdness lately with passwords. I've dropped my previous ISP and as such the old email address. I've been going through and updating sites with my gmail email addresses and some sites want to send an email for confirmation to the gmail address. Click the button and nothing comes in. Try again several times and nada. Camaros.org is one of them. I'm wondering if Gmail doesn't subscribe to a RBL (realtime blackhole list) to block certain sender domains that are known SPAM sources. You can easily get your domain added to this list without even knowing it if you don't have the right security settings in place and then the spammers use the domain as a relay point. Camaros.org is basically an unsecure site (no SSL enabled) so maybe.
