Some Anti-Spam Vendors Blocking and Slowing Gmail

fiorenza writes "Google's Gmail (and corporate mail) are being throttled and sometimes blocked by some anti-spam services, including MessageLabs and Antigen. Ars Technica reports that the blocking is a result of the Google CAPTCHA crack, which has allowed a deluge of spam from Gmail's clusters. Most users won't get blocked mail, but Ars confirmed with MessageLabs that Gmail delivery delays are to be expected."
