Seems Google have serious problems with gmail.com

It started about a week ago, gmail.com started an agressive rate limiting (DEFER), seems gmail.com have serious problems regarding to all of our and customers server log.

(host alt1.gmail-smtp-in.l.google.com[209.85.233.27] said: 421-4.7.28 [xxx.xxxx.xxx.xxx      15] Our system has detected an unusual rate of 421-4.7.28 unsolicited mail originating from your IP address. To protect our 421-4.7.28 users from spam, mail sent from your IP address has been temporarily 421-4.7.28 rate limited. Please visit 421-4.7.28  https://support.google.com/mail/?p=UnsolicitedRateLimitError to 421 4.7.28 review our Bulk Email Senders Guidelines. r7si22638516lji.136 - gsmtp (in reply to end of DATA command))

I have to mention that the unusual mails are hardly reduced due holidays and we are speaking about 5 /hr. at maximum on this server.

If I have to guess, gmail is under massive attack.

Until they fix the issues our users reported the following problems:
 - Password recovery loop
 - Delayed Emails
 - Login Error
 - Unable to send email

Related to our services, if you have gmail address registered please be patient.
