Subject: Patch to rmail to elliminate need for snprintf
To: sendmail@CS.Berkeley.EDU
Date: Thu, 19 May 1994 11:27:16 -0400 (EDT)

I have written the following patch to rmail which removes the requirement
for snprintf while maintaining the protection from buffer overruns.  It also
fixes it to compile with compilers which don't understand ANSI function
prototypes.  Perhaps this should be included in the next version?
