ne peut pas envoyer de courrier à localhost avec postfix: échec de la recherche temporaire

J'ai enlevé postfix, essayé Apache James , enlevé James et je ne peux plus faire fonctionner postfix à nouveau:

à ma connaissance, j'utilise correctement postfix de la manière suivante:

thufir@dur:~$ 
thufir@dur:~$ telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
220 dur.bounceme.net ESMTP Postfix (Ubuntu)
ehlo test
250-dur.bounceme.net
250-PIPELINING
250-SIZE 10240000
250-VRFY
250-ETRN
250-STARTTLS
250-ENHANCEDSTATUSCODES
250-8BITMIME
250 DSN
quit
221 2.0.0 Bye
Connection closed by foreign Host.
thufir@dur:~$

Le problème est peut-être que sendmail ne fonctionne pas: 

thufir@dur:~$ 
thufir@dur:~$ postfix sendmail
postfix: error: to submit mail, use the Postfix sendmail command
postfix: fatal: the postfix command is reserved for the superuser
thufir@dur:~$ 
thufir@dur:~$ Sudo postfix sendmail
postfix/postfix-script: error: unknown command: 'sendmail'
postfix/postfix-script: fatal: usage: postfix start (or stop, reload, abort, flush, check, status, set-permissions, upgrade-configuration)
thufir@dur:~$

Telnet donne:

thufir@dur:~$ 
thufir@dur:~$ telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
220 dur.bounceme.net ESMTP Postfix (Ubuntu)
helo localhost
250 dur.bounceme.net
mail from:thufir@localhost
250 2.1.0 Ok
rcpt to:thufir@localhost
451 4.3.0 <thufir@localhost>: Temporary lookup failure
quit
221 2.0.0 Bye

thufir@dur:~$

qui semble définitivement intriguant.

ok, c'était un problème avec l'installation de postfix. J'ai corrigé un fichier de configuration, supprimé et réinstallé:

root@dur:/etc/postfix#
