I had made a dpkg --purge apparmor and dovecot-common, because there were remaining files, and then I rebooted my server.
After that, the ISPconfig webpanel saids that everithings it´s ok, (I do not trust it so much ehehehe) but when I try to test the POP connection, runing a telent in port 110,
I get the follwoing message in the system log:
Jun 16 07:49:42 wig authdaemond: authpam: username 'firstname.lastname@example.org' not found in password file
I hope that "passord file" is a manner of speech, because courier-authdaemon is supposed to uses PAM to read the encrypted password on the dbispconfig database .... Am I right?
