Three existing solutions (that I know of), take your pick:

1. Install the IDA patches.  Among the patches are routines to do this.


2. Use this script to do your debugging (this came across the net some
   time ago; sorry I don't remember who provided it):

#! /bin/sh
#
# This shell script runs sendmail in address test mode and converts the
# debugging output to something more intelligible for helping debug sendmail.cf
# files.
# 
# Pass the config file to use as $1
#
# Enter input of the form (same as for "sendmail -bt"):
# 
#       0 address1
#       0 address2
#       ...
#       (eof)
# 
#
/usr/lib/sendmail -bt -C$1 -d21.12 |\
grep -v -e '----- rule fails' |\
sed -e 's/-----trying rule:/R/' \
    -e 's/"^P"/$*/g' \
    -e 's/"^Q"/$+/g' \
    -e 's/"^R"/$-/g' \
    -e 's/"^S\([A-Za-z]\)"/$=\1/g' \
    -e 's/"^T\([0-9]\)"/$\1/g' \
    -e 's/"^U"/$#/' \
    -e 's/"^V"/$\&/g' \
    -e 's/"^W"/$:/g' \
    -e 's/"^X"/$>/g' \
    -e 's/"//g' |\
sed -e '/^R/s/[ 	]//g' \
    -e '/matches:/s/[ 	]//g' -e 's/rulematches:/rule matches: /' \
    -e '/rewritten as:/s/[ 	]//g' -e 's/rewrittenas:/rewritten as: /' \
    -e '/returns:/s/[ 	]//g' \
    -e 's/.*ruleset\([0-9]\)returns:/ruleset \1 returns: /' \
    -e '/input:/s/[ 	]//g' \
    -e 's/.*ruleset\(.*\)input:/ruleset \1 input: /'


3. Install these changes in util.c:xputs().  You'll have to do it by
   hand; I have too many changes to too many versions to be able to
   produce a usable context diff.  Again, I don't remember the original
   author of these changes.

Change:
  		}
  		if (c < 040 || c >= 0177)
  		{
! 			(void) putchar('^');
  			c ^= 0100;
  		}
  		(void) putchar(c);

To:
  		}
  		if (c < 040 || c >= 0177)
  		{
! 			switch (c) {
! 			case MATCHZANY:	/* match zero or more tokens */
! 				fputs("$*", stdout);
! 				continue;
! 				break;
! 			case MATCHANY:	/* match one or more tokens */
! 				fputs("$+", stdout);
! 				continue;
! 				break;
! 			case MATCHONE:	/* match exactly one token */
! 				fputs("$-", stdout);
! 				continue;
! 				break;
! 			case MATCHCLASS:/* match one token in a class */
! 				fputs("$=", stdout);
! 				continue;
! 				break;
! 			case MATCHNCLASS:/* match anything not in class */
! 				fputs("$~", stdout);
! 				continue;
! 				break;
! 			case MATCHREPL:	/* replacement on RHS for above */
! 				fputs("$", stdout);
! 				continue;
! 				break;
! 			case CANONNET:	/* canonical net, next token */
! 				fputs("$#", stdout);
! 				continue;
! 				break;
! 			case CANONHOST:	/* canonical host, next token */
! 				fputs("$@", stdout);
! 				continue;
! 				break;
! 			case CANONUSER:	/* canonical user, next N tokens */
! 				fputs("$:", stdout);
! 				continue;
! 				break;
! 			case CALLSUBR:	/* call another rewriting set */
! 				fputs("$>", stdout);
! 				continue;
! 				break;
! 			case CONDIF:	/* conditional if-then */
! 				fputs("$?", stdout);
! 				continue;
! 				break;
! 			case CONDELSE:	/* conditional else */
! 				fputs("$|", stdout);
! 				continue;
! 				break;
! 			case CONDFI:	/* conditional fi */
! 				fputs("$.", stdout);
! 				continue;
! 				break;
! 			case HOSTBEGIN:	/* hostname lookup begin */
! 				fputs("$[", stdout);
! 				continue;
! 				break;
! 			case HOSTEND:	/* hostname lookup end */
! 				fputs("$]", stdout);
! 				continue;
! 				break;
! 			}
! 			putchar('^');
  			c ^= 0100;
  		}
  		(void) putchar(c);


Happy sendmail debugging, if that isn't an oxymoron.
