I've designed a mail sender using java and front-end instances that can send ~70-80 mails /second (i sometimes over-hit that 4900 mails/minute that is enforce by Google)(Using 5 front-end instances and thread-safe activated) If you are not send mails single thread i suggest you read about another but I've encountered ( http://code.google.com/p/googleappengine/issues/detail?id=5769 - appears when you try to send 2 mails in the exact same millisecond or something like that) I've seen that 20 seconds delay in some of my tasks execution, but only in queues that have a low number of tasks in them (1-5).
