DNS dotaz e-mailem

[Tomas Mueller]

Ahoj!

Kdysi fungoval mailserver dns at grasp.insa-lyon.fr, ktery odpovidal
na dotazy DNS zaslane e-mailem. Dneska mi vraci tohle:

... while talking to yseult.sis.pasteur.fr.:
>>> RCPT To:<dns at grasp.insa-lyon.fr>
<<< 553 <dns at grasp.insa-lyon.fr>... Service closed
550 dns at grasp.insa-lyon.fr... User unknown

Nevedel by prosim vas nekdo, zda nekde existuje fungujici mailserver,
ktery na dotaz zaslany e-mailem vrati k zadanemu domenovemu jmenu
IP adresu?
