dpkg: error processing postfix (--configure)

[Thufir]

While it does seem that postfix is running:

thufir at dur:~$ 
thufir at dur:~$ telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.

221 2.0.0 Bye
Connection closed by foreign host.
thufir at dur:~$ 


the install seems wrong, in that "aptitude install postfix" doesn't 
cleanly return results that postfix was installed.


thanks,

Thufir
