Check your spam status
The second tool is the most interesting and certainly required the most work. It's taking the ideas developed in these two posts about checking your rbl/spam status and automating the process to their logical conclusion. This second tool allows scheduled checking and automated updates of any change. At present it checks 75 real-time blacklists of varying degrees of importance. Furthermore it will check these lists up to once a week on your behalf.
It's a simple tool but it's easy to use and should be a big time saver. Expect more of the same . . . soon.
p.s. - I already have some ideas for additional tools but if you are having trouble finding a tool you think will make your life simpler then get in touch as I may be interested in building it as a part of this site. Easiest way to contact me is via a comment. If you don't want it to be public just state you want it to remain private in the message.
