>>I am using one of my Gmail accounts as an SMTP server in a monitor application that I have. It all works really well until it stopped working (isn't that how if always is).

Yes I am sure it got locked out because I sent over 1000 emails through my monitor application in a couple of weeks. I am just having a hard time finding documentation from GMail about this.
