If you are trying to send the emails directly from the process serving your web 
API, then this is absolutely the wrong approach, and you should give up 
immediately on trying to do that.  Your API process should just queue the 
messages to be sent by a separate background process, and then return 
immediately such as with a message "3000 messages queued to be sent soon, click 
here to check queue progress" or such.  Sending in-process may be reasonable for 
a single email, eg email a copy of the form the user just submitted, but that's 
it. -- Darren Duncan
