The setup

Recently, I did some pro-bono consulting work for a client. As part of our agreement I made it clear that I would retain the rights to the code I wrote. The reason I did this is because I wanted to be able to give back to the community, and now I am going to do that. The work was made up of six tasks, ranging from trivial to complex. I intend to write six articles based on these tasks. This is the first.

Recently, I had trouble with the Mambo contact component. Sometimes, the emails would get through, and other times they would not. There did not appear to be any discernable pattern. In the end, I discovered that an innocent looking word in the subject of the email was causing the message to be blocked by some spam filters.
