Only the user part of the triplet is passed to the recipient rulesets.

Here's an example:  Let the rewrite rule for your UUCP mailer be 26.
Then after ruleset 0 determines selects this UUCP mailer the "From:",
"To:", and recipient lines are rewritten.  The "From:" line is passed
through 3,1,26,4.  The "To:" line is passed through 3,2,25,4.  The
user part of the triplet (the recipient) is passed through 3,2,25,4.

This means that the recipient address goes through the canonicalization,
etc. twice.  You might think of it as being passed through rulesets
3,0,3,2,25,4.  But as stated above only the user part of the triplet
gets passed from ruleset 0 to the second occurance of ruleset 3.

Unfortunately, you cannot give 0,2,25,4 directly to the sendmail debuger.
If you do, the subsequent rulesets get the mailer and host part of the
triplet, which just confuses things.  You have to do the second pass
throught the rulesets manually.

These comments are based on my experience with sendmail under SunOS 3.2
and 4.0.
