Thanks Mat, I will try again. I knew there was probably a catch, but the docs I read didn't spell it out. I was actually amazed at how easily it installed. Even the command line interface is just easy to use. I also noticed there is a C library for this package. It would be nice to compile this into an AOLserver module, but using exec might not be too bad either. Your tcl module could stuff data into the db and run the command, then you avoid having to write the pg to vpopmail code. I'm just guessing, I better read your ideas in more detail.
