Hi Ben!

Thanks to your reply, I was able to make great headway in getting this 
to work :)

I still have one error message I can't solve - but first, this is what I 
did to move things along...

As I mentioned offline to Geof, I already figured out the Sendmail MTA 
wasn't getting the mlmmj program call, as you suspected. I've made all 
references to my domain and email list below generic, to make things 
easier to read.

I tried your suggestion by replacing the aliases entry program-call for 
mlmmj, with a simple "cat" command to determine if this was a Sendmail 
issue, or mlmmj... turns out the "cat" command would not fire either.

Here's what I did to get Sendmail to successfully fire the basic "cat" 
command:

- I added an entry to the /etc/mail/virtusertable file:

  listname@mydomain.com   listname.mydomain.com


- then I changed the entry in the /etc/aliases file:
   from:

     listname: "|cat > /tmp/mailtest.txt"

   to:

     listname.mydomain.com: "|cat > /tmp/mailtest.txt"


Presto!  The "cat" command fired when I sent an email to 
listname@mydomain.com.

(*NOTE: this differs from the README documentation on the mlmmj website; 
which has the aliases entry displayed as "listname: xxxxxxxx" instead of 
"listname.mydomain.com:     xxxxxxx" - I'm not sure if this is Sendmail 
specific, or if this may be important for other MTAs as well... )

So now I had Sendmail set correctly to potentially fire the mlmmj 
program, so I tried this /etc/aliases entry:

listname.mydomain.com: "|/usr/local/bin/mlmmj-receive -L 
/var/spool/mlmmj/listname"

It did get as far as trying to call mlmmj-receive, but it failed to 
start mlmmj-receive:

Oct 15 18:45:22 cloud smrsh: uid 8: attempt to use "mlmmj-receive -L /var/spool/mlmmj/listname" (stat failed)

Oct 15 18:45:22 cloud sendmail[4560]: s9FIjLBe004558: to="|/etc/smrsh/mlmmj-receive -L /var/spool/mlmmj/listname", ctladdr=<listname@mydomain.com> (8/0), delay=00:00:00, xdelay=00:00:00, mailer=prog, pri=35725, dsn=5.0.0, stat=Service unavailable

Oct 15 18:45:22 cloud sendmail[4560]: s9FIjLBe004558: s9FIjMBe004560: DSN: Service unavailable

smrsh: "mlmmj-receive" not available for sendmail programs (stat failed)
554 5.0.0 Service unavailable


So here's what I did to get mlmmj-receive to fire through the restricted 
shell utility smrsh:

- I created symlinks for the mlmmj-xxx executables in the /etc/smrsh 
directory:

  ln -s  /usr/local/bin/mlmmj-xxxxx


Now mlmmj-receive executes when I send an email to listname@mydomain.com!

Unfortunately, I'm now getting the following bounce-error message:

    ----- The following addresses had permanent fatal errors -----
"|mlmmj-receive -L /var/spool/mlmmj/listname"
     (reason: 1)
     (expanded from:<listname@mydomain.com>)

    ----- Transcript of session follows -----
Have to invoke either as root or as the user owning listdir
554 5.3.0 unknown mailer error 1


The symlinks and the actual mlmmj-xxxx files are all chmod as 755, but 
I'm not sure how or where to effect a permissions change to get sendmail 
to "invoke" mlmmj-receive with the proper permissions.

As you can see, this is progress from where I was before... any ideas on 
how I should address the permissions error coming from mlmmj-receive?
