What filesystems do not support the characters appearing in valid message

Windows and VMS. Since message-ids are used for annotations, I
get around this problem by encoding the message-id in quoted-printable
format. However, for VMS, there are filename length limitations, which
most message-ids easily exceed. I think I will not bother with
trying to deal with filename length issues since the user base is
very small for such systems.
The quoted-printable trick should be sufficient for special character
issues, but it does add a little overhead.
As a temporary measure, you could use a CGI program that took the message
ID as a parameter, and retrieved the appropriate filename using the
information from .mhonarc.db. That would resolve the problem of invalid
filenames by giving you a persistent method for retrieving messages
independent of the filename.
This is inefficient, but will work. A more efficient approach is
to use a db, or dbm, file that maps message-ids to pathnames. It is
possible to hook such a thing in with the new callback functions
added in v2.5. Perl has modules for interfacing with various db file
types.
