I'd say that Googles behaviour in this instance is stupid and somebody
influential should get them to fix it at their end. Exim should
naturally still deliver all of these messages, but there will be delays
as per the retry rule configuration. This is going to affect a *lot* of
systems and generate a lot of complaints to Google.
