We sent out an email yesterday, and nearly all of the 57 "non-existent" emails that bounced were from either sbcglobal.net or att.net. Not only is this an extremely high number of non-existent email for our list, but to have that many from just two email providers is extremely odd.

My perception is that these emails are actually still fine, but that there is some sort of glitch. I recall something like this happening on a large scale a few years ago with Yahoo email addresses, too.
