but that script is almost certainly hiding a lot of the complexity (like the AppEngine API does) preparing and starting a message on its journey is a very small part. Once the mail has passed from the application it needs to enter the a mail queue (of some sort) and from there be sent on its way. That involves looking up the relevent mail server and sending it on. But a big part of it is dealing with when that server is down, or otherwise unavailable, or simply refuses your email, you either need to queue it and retry later, or send a bounce to the sender. Another big issue once you start sending large quantities of messages - you start getting tarpitted or otherwise blacklisted by mail servers. Esp. relevent once you start sending 'system generated' messages that are by nature repetitive - its quite easy for these to trigger spam measures. Also any service (elsewhere or appengine itself), that allowed easy (and esp free) mass mailing would be ripe target for spammers > > The specific problem with Google App Engine is that there are > excecution time / cpu limits (per request), and there are also email > limits (2000 per day). > > On Dec 19, 5:33 am, Greg <g.fawc...@gmail.com> wrote: >> On Dec 19, 1:00 pm, MajorProgamming <sefira...@gmail.com> wrote: >> >> > 1.
