That's a symlink. Next step, what does 'ls -l /usr/exim/bin/exim-4.20-1' say?

config-test is just a Perl script, so it's easy enough to scan through it
and find out what it's trying to do at the point where it gives that error
(this taken from majordomo 1.94.5):

print "Attempting to verify that this is a valid mailer...";
if ( -x $x ) {
    print "looks okay.\n";
} else {
    print "nope, $x is not executable\n";
    $BAD++;
}

So it's the perl '-x' operator it's using, which tests whether the target is
executable, *by the current user*. Since you have switched uids using
./wrapper to the majordomo user, you have to be sure that exim is executable
by that user. But unless you have fiddled with permissions, it will be.

On my laptop (FreeBSD-4.8) I have:

$ ls -l /usr/exim/bin/exim
lrwxr-xr-x  1 root  wheel  11 May 19 22:54 /usr/exim/bin/exim -> exim-4.20-1

$ ls -l /usr/exim/bin/exim-4.20-1
-rwsr-xr-x  1 root  wheel  592502 May 19 22:54 /usr/exim/bin/exim-4.20-1
   ^     ^
   |     `- executable by everyone
 setuid
  root

$ perl -e 'print (-x "/usr/exim/bin/exim")'
1

So it works OK for me.

Regards,

Brian.
