Today the system was effectively down because I was hit with thousands of emails in a very short period of time. Causing a huge backlog which I had to clear to bring the system back up. (Clearing my email queue has the effect that any notifications in the queue are never sent :( )
Please do not do this. If you need to send many SMSs please contact me and I will tell you how to do it without bringing the system down. (use the API)
I have put in place a spam detection, which will now log your account information and allow me to blacklist google voice accounts and phone numbers, tonight I will be blacklisting whoever was responsible for the flood of emails, unless I hear from them before then.
