I seem to have a problem when people register on my site using a @comcast.net, or @yahoo.com (so far those are the only 2) email address. The confirmation email never gets to them. I have tested this personally with my comcast email account, on THIS site, and my own. (You guys can delete Round11_Test). I never get the confirmation email. I got it right away to my gmail account, and I have no problem sending mail from my domain name email account to my comcast.net email account. Maybe I should switch to SMTP email instead of having the server do it for me? Anyone else seen this issue?
