Please read and let me know what you think. This site is still under development, which it probably will always be. But hang in there, should be cool.
Ok, so I was using amavisd to help me out with scanning for viruses and spam. I wanted MySQL tables for everything, but i was configuring everything so I could prefix those tables to fit into my control panel scheme. (by default their table names are lame, and as far as I know, un-prefix-able). So to use my scheme, I override the default sql used to query for various things, then I can use my own table names.
The problem I encountered was when I upgraded amavisd to the newest from the repository. Suddenly all of my mail was getting deferred and infinitely queued.
