Sendmail nefunguje

[Petr.Balner na opa.os.ds.mfcr.cz]

Preju pekny den, 
nefunguje mi Sendmail (8.11.2) (dorucovani/odesilani mailu)a v postovnim logu se mi objevuji prilozene hlaseni. 
Nemohl by me nekdo navest v cem by mohla byt chyba - anebo je nutna rovnou preinstalace. 
Tato hlaska se mi objevuje uz delsi dobu a nevim jaka zmena v systemu ji mohla zpusobit.
Mam os:RH 7.1
Diky Petr
