### Thanks for your reply. After looking at the examples, I realized that
### you're not doing what I want, which is to store the messages on the local
### hard disk with the same message number as what was on the remote. So, I
### rolled my own program, although I haven't finished it yet (I have a hook
### for expiring, but haven't done it yet).
###
### You are welcome to use this in the Net:: distribution if you think it is
### useful.
