Odd permissions problem with Sendmail and Smartlist

[Gregory Gulik <greg gulik org>]

I'm trying to migrate some Smartlist mailing lists from an old SPARC 
Ultra 2 to a new RH9 based server.

One annoying problem I've run into is getting Smartlist running.  I 
compiled and installed the latest Smartlist then moved the list over but 
I'm getting a strange problem with Sendmail being unable to run the 
"flist" program which is setuid to the "list" user id.

Here is a test message I've tried to run:

Jun  2 12:03:31 server2 sendmail[6336]: h52H3VBP006336: from=root, 
size=48, class=0, nrcpts=1, 
msgid=<200306021703 h52H3VBP006336 server2 gagme com>, relay=root localhost
Jun  2 12:03:31 server2 sendmail[6338]: h52H3Vo9006338:

dsn=2.0.0, stat=Sent (h52H3Vo9006338 Message accepted for delivery)
Jun  2 12:03:32 server2 smrsh: uid 8: attempt to use "flist mylist" 
(stat failed)
Jun  2 12:03:32 server2 sendmail[6339]: h52H3Vo9006338: to="|exec 
/home/list/.bin/flist mylist", ctladdr=<mylist server2 gagme com> (8/0), 
delay=00:00:01, xdelay=00:00:00, mailer=prog, pri=30562, dsn=5.0.0, 
stat=Service unavailable
Jun  2 12:03:32 server2 sendmail[6339]: h52H3Vo9006338: h52H3Wo9006339: 
DSN: Service unavailable

The alias in /etc/aliases looks like this:

gmylist: "|exec /home/list/.bin/flist mylist"

The flist program permissions are:

-r-sr-sr-x    5 list     gulik       20920 Jun  2 10:53 flist

When I try to run it manually I get:

[root server2 .bin]# ./flist mylist
flist: Strange group or user id

Any attempt to E-mail the list returns with a bounce to postmaster with 
the following error:

The original message was received at Mon, 2 Jun 2003 12:35:18 -0500
from server.gagme.com [192.168.1.2]

   ----- The following addresses had permanent fatal errors -----
"|exec /home/list/.bin/flist mylist"
    (reason: Service unavailable)
    (expanded from: <mylist server2 gagme com>)

   ----- Transcript of session follows -----
smrsh: "flist" not available for sendmail programs (stat failed)
554 5.0.0 Service unavailable


Any ideas????  This is driving me nuts and it's one of the last things 
on the todo list that need to work before I can cut over....
