Okay, I guess I should clarify what I mean by message ID numbers. PHP downloads the messages over POP3 as you would using telnet. The message IDs that it uses are just like you would using the command line to read mail:
LIST +OK 15 70871 1 5427 2 1826 3 16834 4 4043 5 3875 6 2373 7 15345 8 1642 9 3229 10 2662 11 3882 12 3052 13 3524 14 1382 15 1775 The problem is that these IDs do not stay the same if new mail arrives. I may be able to re-write the program to use the "Message-ID: " header, if this is unchangeable. If someone has a better suggestion, let me know. Dustin C.
