Each line of output produced during rule testing begins with an indication of the rule set number or name being processed:
canonify input: Bill Bix < bill >
precedes each address that is about to be processed
by a rule set:
input:Bill Bix < bill >
precedes each address that is the result of
rewriting by a rule set:
When rule sets call other rule sets as subroutines,
those calls are shown in the output with
returns pairs. In the
Canonify2 rule set is called as a
subroutine rule set from inside the
canonify rule set
canonify input: Bill Bix < bill > Canonify2 input: bill Canonify2 returns: bill canonify returns: bill
The output can also contain rule set operators:
In this output, the operators are printed as they
would appear in the configuration file. The
$# selects a delivery
agent, and the
specifies the user. Under old versions of
sendmail, those operators are
printed in the output as control characters:
rewrite: rule set 0 returns:
The correspondence between control characters in the old-style output and sendmail configuration file operators is given in Table 8-2.
