nedorucitelne maily

[Petr Hvezda]

Zdravim konferenci,
 
po zmene IP adresy (providera) u mailoveho serveru se mi v logu objevuji
dosti podivne veci:
 
Nov  8 14:46:43 mail sendmail[7979]: kA8DhhhO007979: ruleset=check_mail,
arg1=<petr.hvezda na unistav.cz>, relay=[80.95.122.66], reject=451 4.1.8 Domain
of send
er address petr.hvezda na unistav.cz does not resolve

Domnival jsem se tedy ze chyba bude v DNS. Tam vsak chyba neni, pouzivam
toto DNS i u jinych serveru a je 100% v poradku. Pokud ze serveru kde je
chyba vykonam prikaz dig, tak se to jevi dobre.
 
dig @mujdnsserver yahoo.com IN MX

V /etc/resolv.conf mam pouze tento jeden server. V /etc/hosts mam akorat
localhost a vlastni IP serveru. Udelal jsem nekde chybu ?
 
Diky
