Re: SRS sendmail integration

I am pretty dense when it comes to sendmail-cf.  I can't get
the NO_SRS_FILE to work.

It generates a class:
# Class of destination mailers not needing SRS
F{noSrsMailers}-o /etc/mail/no-srs-mailers %[^\#]

And MakeSrs looks like this:

SMakeSrs
#
# Prevent SRS encapsulation if "To" address is SRS
R$*                             $: $1 $>IsSrs $&u
R$* YES                         $@ $1
R$* NO                          $: $1
#
# If destination mailer is in non-SRS list, do not apply SRS
# This is intended for handling communication between secondary MX and
# primary MX
R$*                             $: $&h $| $1
R$={noSrsMailers} $| $*         $@ $2
R$* $| $*                       $: $2
R$*                             $: $(make_srs $1 $)

The no-srs-mailers file has hostnames in it (changed to protect the innocent):

# no-srs-mailers - list domains we should not SRS encode for when we
# send to them.  E.g. primary MX servers for which we are a secondary.
#
mycust.com
anothercust.com

When I send mail to [email protected], the message is still SRS encoded.
It looks like $&h would be mycust.com, and it should exit the
subrout early - but somehow make_srs is still called.

Do I have the format wrong?  Or does $&h mean the *source* host?
Why would I want to not SRS encode certain source hosts?  (That
would be covered by NO_SRS_FROM_LOCAL, right?)

How do you trace cf macros to try and debug them?
