Courier upgrade

[Nathan Friess <natmanz@shaw.ca>]

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
