Postfix problem

[morsta]

My mailserver has been working perfectly until today, and i can´t figure out what is wrong.
Students can log into webmail, but are unable to send mail.
The squirrelmail configtest reports everything to be OK, allthough the smtp-check takes about 90 seconds.

mail log:
Feb 16 14:08:38 Leonardo postfix/smtpd[2423]: fatal: unsupported dictionary type: http
Feb 16 14:08:39 Leonardo postfix/master[2015]: warning: process /usr/libexec/postfix/smtpd pid 2423 exit status 1

Help is greatly appreciated
