Sendmail vraci permissions denied pro jine users nez root.

[dmichal na altien.com]

Zdravim,
zapasim se sendmail na CentOS. Kdyz se prihlasim jako root, pak:

echo pokus | mail -s "test mail" dmichal na altien.com
- ok email dorazi

Pak si dam su dmichal (nebo jakehokoliv jineho usera) a ten samy prikaz
na odeslani emailu a dostanu reply:
/usr/sbin/sendmail: Permission denied

Zpatky na roota a:
[root na agw_new mail]# ls -l /usr/sbin/sendmail
lrwxrwxrwx  1 root root 21 Dec  5 14:01 /usr/sbin/sendmail ->
/etc/alternatives/mta

takze:
[root na agw_new mail]# ls -l /etc/alternatives/mta
lrwxrwxrwx  1 root root 27 Dec  5 14:01 /etc/alternatives/mta ->
/usr/sbin/sendmail.sendmail

ok moc nechapu duvod tech linku ale ok:
[root na agw_new mail]# ls -l /usr/sbin/sendmail.sendmail
-rwxr-sr-x  1 root smmsp 733912 Jun 14  2006 /usr/sbin/sendmail.sendmail

Zda se ze prava jsou v poradku a jine misto kam se podivat nevim. Mozna
je to nekde v nastaveni sendmailu, ale nevykoukal jsme kde by to mohlo
byt.

Mate nekdo nejaky napad kam se podivat?
