Hi ! For whatever reason logging of wrong Dovecot stopped working (possibly after upgrade of ISPConfig to 3.13 or Debian 9 security patches), but unfortunately I can't say for sure. tail -n 1000000 /var/log/mail.log | grep pop3-login | grep failed shows failed entries, however tail -n 1000000 /var/log/mail.log | grep mismatch shows nothing - no recorded bogus passwords. Options in /etc/dovecot/conf.d/10-logging.conf auth_verbose = yes auth_verbose_passwords = plain auth_debug_passwords = yes What is a cause of such problem? Thanks in advance for any suggestion(s).
Settings in /etc/dovecot/conf.d/* files are not used on an ISPConfig server. Add settings in dovecot.conf file if you want to change something and make it update safe by copying the appropriate modified template from install/tpl/ of the ISPConfig tar.gz to the /usr/local/ispconfig/server/conf-custom/install/ folder.
