Converting existing hypermail archives to use a different HTML file suffix:
===========================================================================
If you are going to change the filename suffix used from the default ".html"
to something else, you must deal with the existing files first. Otherwise,
hypermail does not know they are there and starts numbering files from the
begining.
 
This means that you need to either start out fresh, regenerate the archive
from an existing mailbox or convert all existing files  and the links within
the existing archive files to use the proper extension.

File Locking On NFS Mounted Directories:
========================================
File locking doesn't work all that well over NFS. For that reason you are
encouraged to run Hypermail on the same system that the disk is on. This
is due to possible timing issues within NFS. Hypermail based network locking 
is not expected to work at this time.

Message Dates:
==============
Dates on messages prior to 1970 are not processed correctly.
