Great! looks like a keeper.

Just one item per line. The only order dependent option I could think
of is the clear_all_flags option. So you could start clean and only
add in exactly what you wanted.

On login I could send
vpopmail_dir /base/path/to/~vpopmail

Gotcha. There is code for validating directory input to restrict each
level of user to their respective base directories. Also it is checking
for ".." in any part of the directory. In case input tries to walk down
to / and trod on any file in the filesystem. Any other things we should
check for? Perhaps "%" in filenames?
