I fixed the EnvFromSMTP - and I'm not even an m4 expert!  m4 uses redirections,
so I changed pysrs.m4 like this:

diff -c -r1.2 pysrs.m4
*** pysrs.m4    24 Mar 2004 01:03:21 -0000      1.2
--- pysrs.m4    24 Mar 2004 22:03:44 -0000

As a finishing touch, I can check that HACK(pysrs) comes after the smtp mailer
by checking that _MAILER_DEFINED_ is defined.

This, however, leaves ParseLocal as follows:

SParseLocal=98

# addresses sent to [email protected] will give a 551 error code
R$* < @ $+ .REDIRECT. >		$: $1 < @ $2 . REDIRECT . > < ${opMode} >
R$* < @ $+ .REDIRECT. > <i>	$: $1 < @ $2 . REDIRECT. >
R$* < @ $+ .REDIRECT. > < $- >	$#error $@ 5.1.1 $: "551 User has moved; please try " <$1@$2>

SParseLocal=98
R$*				$: $>ReverseSrs $1

This can be fixed by providing a feature which does

LOCAL_RULESET_0
R$*				$: $>ReverseSrs $1

and must come before redirect.

However, is this really necessary?  It looks like adding REDIRECT has
already been done before entering ParseLocal. And the ReverseSrs would
not do anything in that case.  On the other hand, if REDIRECT has *not*
been added, then ReverseSrs will work normally.
