Thanks for your reply, Supposedly the bucket_size: should be 1 and not 8 according to this post http://groups.google.co.uk/group/google-appengine/browse_thread/thread/3d64511a517cffc1/64fe290597597511?lnk=gst&q=mail+taskqueue#64fe290597597511
But I tried it anyway and it had no effect, it's still sending out about 10 emails per _second_ in my test, instead of the 8 per minute that I need. I don't think the second alternative would work either since there is a time limit of 30 seconds per request and it would probably trigger a deadline exceeded exception. http://groups.google.co.uk/group/google-appengine/browse_thread/thread/28e7ecde894c59a9/896fbdcf0d836296?lnk=gst&q=mail+taskqueue#896fbdcf0d836296 Surely there must be some way to get App-Engine to send out emails at a certain rate without hitting the OverQuotaError? Anyone who successfully implemented it?
