[Sendmail] stat: data format error

[Rembrand20]

Beste tweakers,

Ik heb sinds kort een probleempje met mijn mail server.
Mijn mailserver is een redhat 9 bak met sendmail 8.12.*.
Als ik een mailje over deze machine stuur is er niets aan de hand.
Maar wil ik lokaal een mailtje sturen krijg ik de volgende fout melding.

code:

Heeft iemand enige idee wat het kan zijn.

[Whizzer]

wat dacht je hier van: "User unknown"....

[Rembrand20]

Ja en dat is dus niet het geval...

Als ik een mailtje naar het zelfde adres stuur komt het gewoon aan...

Heb het opgelost was iets met dns naampje
