Starting this weekend, mail sent from a google apps domain to a user on my server who has her email forwarded to a google.com address has the email deferred forever with a possibly spurious message:
** relay=alt4.gmail-smtp-in.l.google.com. [64.233.186.27], dsn=4.0.0, stat=Deferred: 421-4.7.0 [129.82.129.115 15] Our system has detected an unusual rate of ** I've seen the rate-limiting message before when spam has gotten through, but it was always temporary and in this case, it is almost certainly not related to spam. Consider an unused account on the google apps domain (blah) and a newly created alias on my server (pm) that forwards to a testing account at google that receives essentially no mail. blah mails to pm, my server accepts it and tries to send it along to the testing account, but google instantly gives the above rate-limiting message and the mail stays in the queue forever. This problem is almost certainly not a problem with blah since it's never used. It can't be with the pm alias because it hadn't existed before. It can't be with my mail server in general because gmail is still accepting mail from it; from a local account, I can send without issue. The cruncher is that if I send to pm from a @gmail.com account rather than a google apps domain account, everything gets forwarded just fine. I've come to understand that email forwarding is going away and I should start preparing people for it. But the odd error message and that fact that it still works from gmail.com addresses has me more than a little perplexed. Did something recently change with google and accepting mail from their apps domains? Any clues greatly appreciated.
