CHECKUIDS
==========
The CHECKUIDS program is a small command-line utility to check the message
UIDs (Unique IDs) in your VPOP3 mailboxes/folders and optionally fix them.

Message UIDs should be unique within a mailbox. During normal operation 
VPOP3 will automatically assign UIDs correctly to messages, but if message
files are copied from other VPOP3 servers, created manually or certain
control files are corrupted, the message UIDs may not be unique.

When downloading using POP3 this does not NORMALLY cause a problem (but this
depends on the email client), but it will cause a problem with IMAP4
downloads.

To run CHECKUIDS, copy CHECKUIDS.EXE into the main VPOP3 directory.
- close VPOP3 down (this is important)
- from a command prompt run 'CHECKUIDS'. This will check for any errors
- if there are errors, run 'CHECKUIDS -fix'. This will make it fix the errors
- restart VPOP3

Note that the '-fix' option has a small limitation. In IMAP4, message UIDs 
should be assigned in order of the messages being received. The '-fix' option
does not check this, so it will probably assign UIDs out of order. This should
not cause any problems, except for possibly the fixed messages being shown in 
the incorrect place in the email client message list.

After running 'CHECKUIDS -fix' you should flush any cached data from your 
IMAP4 email clients to force the client to resynchronise with VPOP3
Enterprise. The method for doing this depends on the email client - in some
cases you may have to remove and recreate the IMAP4 email account totally,
but check the email client documentation first
