Hello,
I recently upgraded a server from Woody to Sarge. When I was running
Woody, I had Courier MTA installed, up to date, and working fine. After
I upgraded to Sarge, any program that used 'sendmail' stopped working.
I fixed this by changing /usr/sbin/sendmail to be set-uid... as follows:
$ apt-cache policy courier-mta
courier-mta:
Installed: 0.47-4
...
-- Before set-uid --
$ ls -l /usr/sbin/sendmail
-rwxr-xr-x 1 root daemon 26328 Jan 26 15:31 /usr/sbin/sendmail
$ echo hi | sendmail me
sendmail: ERR: submitclient: EOF from submit.
432 Service temporarily unavailable.
-- Now --
$ ls -l /usr/sbin/sendmail
-rwsr-xr-x 1 root daemon 26328 Jan 26 15:31 /usr/sbin/sendmail
$ echo hi | sendmail me
$
I don't know if sendmail was set-uid before I upgraded. Was this the
correct thing to do? Should Courier's sendmail normally be set-uid? If
so, why wasn't it that way when I upgraded? (a bug?)
Thanks,
Nathan
