       After being bitten by the UUCP mailer bug three times this
       morning,  I decided to try and do something about it.  

Recap: The UUCP mailer will go into an infinite loop, filling up all
       available space on the UUCP_DISK if it encounters an incoming 
       mail input file with any lines in the header more than 255 
       characters in length.

Solution: 

       Trying to make this as simple as possible, I did the following.

       1 - Wrote a C program to read an input file and return 0 
           if any line in the file was greater than 255 characters.
           This was a quick and dirty program that simply opens the
           file in binary stream mode and counts the number of characters 
           between occurrences of any one of \000, \n or \r.

           The program returns 1 in all other cases.

       2 - Modified UUXQT_DCL.COM so that just before it invokes the
           UUCP RMAIL portion of the command procedure it runs the
           file through this program.  If the program returns 0, I have
           that part of the command procedure goto FAILED_RMAIL_1.
           This handles mailing a message to the local POSTMASTER and
           gets the files out of the way.

       After testing and tweaking it for the better part of the day I
       concluded that this method seems to work.  I mailed myself
       copies of the files that started the problem earlier, and it
       worked as expected.

       If anyone can see a major flaw in this reasoning, let me know.

       If it looks like it should work and you'd like a copy of the C 
       and COM files, also let me know.
