I asked about sendmail testing with perl.  Here's the results.
Thanks to everybody for the help.

Subject: Perl Package to test Sendmail.cf?

I wrote a shell script to do this, and said I wanted to use perl.
It was in the Ease distribution.

Sun's sendmail documentation does say so, but the Berkeley documentation
doesn't.  It does happen in Berkeley sendmail as well.

X
Ahh, maybe that's our source of confusion.  Mine does all this too.  The
problem is that the first section ("Mail address resolution (rule 0)") is
incomplete.  Addresses here are only being passed through 3 and 0.  But at
the end of 0, the $: section is then passed through S and 4 before being
passed to the mailer as $u.  That's what checksendmail isn't doing.
X
Do you read comp.mail.sendmail?  There has been a bit of discussion about
this in the last couple of weeks (since I asked the question).  Some people
say it's passed through 1 or 2 before S and 4, but I haven't been able to
confirm that.
X
To clarify further, this is what happens to the envelope address:
X
X             /  $# mailer ->
address -> 3 -> 0 -> -- $@ host -> $h
X             \  $: user -> S -> 4 -> $u

X
Right.  I'll explain it here in e-mail since you can look over it in text,
but feel free to call if you want - [phone].
X
The problem is that the lower transformations move the address through, say
X
X    3 -> 1 -> S -> 4
X
So it doesn't pass through 0.  Furthermore, the transformations I'm talking
about, the ones that are missing, are not the entire address - it's only the
local-part as determined by 0.
X
> I'm sure you're right -- I just need to talk about it to be sure.
X
If you have a SunOS 4.x manual set, check out the sendmail guide.  It's not
well explained in there, but it *is* in there.  Or ask on
comp.mail.sendmail; maybe someone else can explain it better.  I wish I had
sources...
X
Anyway, I expect to be in my office all afternoon (east coast).

Thanks to Gene Kim for his assistance in creating the PERL script.

There is still a slight, almost never noticeable bug in the way the
from address is set up while still parsing rule 0.  I'll try to fix it
by the 9/91...RK

.B checksendmail
[
.B \-C
.I file.cf
] [
.B \-r
.I resolve
] [
.B \-t
.I towhom
] [
.B \-f

.SH DESCRIPTION
.LP
The
.B checksendmail
program is a
.B perl
script that aids the testing of
.B sendmail's
various configuration files.
.B checksendmail
passes typical addresses (supplied in input files) through
.B sendmail
and prints the results of the resolution and transformation routines.
.LP
The input files contain a list of addresses, one per line.
Here is an example:
.RS
.nf
user
user@site
[e-mail]
.fi
.RE
.SH OPTIONS
.TP 16
.BI \-C " file.cf"
Use the
.B sendmail
configuration file
.I file.cf
instead of the default
.B "/etc/sendmail.cf"
file.
.TP
.BI \-r " resolve"
Use
.I resolve
as the input file for the addresses to be used for mail resolving.  Defaults
to
.BR address.resolve \|.
.TP
.BI \-t " towhom"
Use
.I towhom
as the input file for the ``from whom'' addresses.
.I towhom
defaults to
.BR address.resolve \|.
.TP
.BI \-f " fromwhom"
Use
.I fromwhom
as the input file for the ``to whom'' addresses.
.I fromwhom
defaults to
.BR address.resolve \|.
.SH EXAMPLES
The following command will pass the addresses in `address.resolve' through
.B sendmail
using the configuration information in
.I myconfig.cf \|.

`From' address transformations for mailer ether:
.sp 0.5
user                        ---->  user
user@site                   ---->  user
[e-mail]               ---->  user
.sp
.fi
.ft R
.RE
.LP
The first section of the output shows how the addresses in the input
files are resolved by
.BR sendmail \|.
Consider the following output line:
.nf
.RS
.ft CW
[e-mail]               --(ether )-->  [e-mail][rmtc]
.ft
.RE
.fi
The input address \f([e-mail]\fP resolves to use the
\f(CWether\fP mailer.  That mailer is directed to send the mail to
to the user \f([e-mail]\fP
at site \f(CWrmtc\fP (as indicated in the square brackets)
.LP
The two later sections of output show how the addresses specified as
the `To' and `From' address are transformed in the text of the
headers.  In the example above, the `To' addresses are untouched.
The `From' addresses, however, all lose their machine information on
the way through the mailer:
.nf
.RS
.ft CW
user@site                   ---->  user
.ft
.RE
.fi
This may be the result when using this configuration file on a
workstation which is to be hidden as a mailhost from the rest of the
network.

Here is a set of addresses used at one site for the purposes of
testing address resolution.  Italics are comments detailing why
particular addresses are present:

Note that
.B checksendmail
is a
.B perl
script.  If your site does not have
.BR perl ,
it can be obtained via anonymous
.B ftp
at uunet.uu.net\|.
.LP
.B sendmail
requires that the user have access to directory specified by the `OQ'
parameter in the configuration file (normally
.BR /usr/spool/mqueue ).
.B checksendmail
verifies that the user has access to this directory before allowing the
test to continue.

Hi,
X
I think your program is great.  I had a little shell script of my own,
but yours is much better.  I have made two changes that are useful:
X
1. I never had any need to access the /var/spool/queue directory in
X   test mode.  I changed the 'die' for a 'warn'
X
2. The 'error' mailer outputs error messages instead of addresses.
X   I modified the parsing to keep the spaces in those messages.
X
Here's the diff file:
