Below are all changes to Internet Rex since v2.00 (complete list from v0.98 is
in file History.Txt). Note in particular changes for v2.31. If anyone has a
specific NEED for any of these changes, contact me via netmail or E-mail at
fido4cmech(aT)bellsouth.net and I will get the Beta to you. I can E-mail files
and/or upload to servers with a password, your choice.

... since Irex is no longer being developed or supported, running the Beta will
be at your own risk, though many are doing so quite successfully .

  of relying on the mail tosser
! UUCP processing in Rex's SMTP daemon can now handle infinite (limited by
  available memory) email address on one C rmail line

  which incorrectly blast data through to still work properly

  which listed the site address after the flag instead of in the BBS name
- resend requests would result in queue entries which never got removed
  when they expired

- workaround for a threading issue with WinServer which could result in Rex
  freezing after a send event where no files were sent (PX/Wins systems only)

  doesn't result in messages delivered with the old format being "lost"
- wdialup.rex wasn't being properly loaded if Rex was run from somewhere
  other than its install directory

  spool with a UUCICO format

  sent in the DOS 16-bit version
- in some cases when an outbound toss failed, Rex could stay logged into

  signal handlers under Linux
- separate Unix spool file messages on From instead of From/from
