GMail hits new levels of being unusable for kernel work:

(host gmail-smtp-in.l.google.com[74.125.200.26] said: 421-4.7.28 Gmail has detected this message exceeded its quota for sending 421-4.7.28 messages with the same Message-ID. To best protect our users, the 421-4.7.28 message has been temporarily rejected. For more information, go to 421 4.7.28 https://support.google.com/mail/answer/188131 me13-20020a170902fc4d00b001e0cd7403a1si1415673plb.79 - gsmtp (in reply to end of DATA command))

Needless to say, this affects delivery of messages sent to multiple mailing lists if the recipient is subscribed to several of them.

Also, as far as error messages go, this is pretty terrible. How can a message exceed a quota? Did it mean node? Recipient?

@monsieuricon It appears to mean the Message-ID. The same Message-ID cannot be used for more than some unknown number of copies of a message, so you're supposed to use a different Message-ID for each recipient and hope it helps? (Doesn't make much sense for discussion lists if you want threading to work.)
