Description of problem:

When smartd sends warning emails it calls the mailer "mail" by default. "mail" itself tries dropping privileges but fails:

Executing test of mail to root ...
Test of mail to root produced unexpected output (66 bytes) to STDOUT/STDERR: 
drop_privileges: setgroups(1, 51) failed: Operation not permitted

... and no mail is actually sent.

This will cause admins detecting disk failures when it's already too late.

Version-Release number of selected component (if applicable):

smartmontools-5.38-13.fc11.i586

How reproducible:

Always

Steps to Reproduce:
1. stop smartd by calling "service smartd stop"
2. Add -M test to a device config in /etc/smard.conf, e.g.:

/dev/sda -d sat -H -l error -l selftest -t -I 9 -I 190 -I 194 -m root -M test

2. call "smartd -d -q onecheck" and watch the output
3. Check root's email
  
Actual results:

no email from smartd

Expected results:

email from smartd

Additional info:

Most probably caused by the "smartmontools-5.38-lowcap.patch".
