ERROR: Connection dropped by IMAP server.

[javierxd]

Estimada comunidad, el problema es el siguiente:
Al intentar ingresar por webmail me sale un error diciendo "Connection dropped by IMAP server." revisando los logs tengo:

Code:

corrí el siguiente comando # /etc/init.d/courier-authdaemond restart
pero nada el problema persiste, ya he intentado casi de todo hasta hice un # perl ispcp-upgrade para restaurar la configuración pero nada.

si alguien tiene una idea de como solucionarlo bienvenida ésta sea y de antemano gracias. espero pronto poner este tema [solved]

Si después de hacer "/etc/init.d/courier-authdaemond restart" sigues teniendo esos errores, es de intuir que ese demonio no puede arrancar por algun problema.

Has mirado si aparece algo en syslog al tratar de arrancarlo? Vamos, que tu terminas viendo los errores que da el cliente imap cuando los usuarios no se pueden autenticar, pero suena a que el problema real lo tiene el courier-authdademon, que no mete sus mensajes de error en el mail.log sino en syslog. En cuanto soluciones eso los errores de mail desapareceran solos...

ok acabo de correr # /etc/init.d/courier-authdaemon restart y esto es lo que aparece en syslog:

Code:

# tail -f /var/log/syslog
Aug 18 12:29:18  authdaemond: stopping authdaemond children
Aug 18 12:29:23  authdaemond: modules="authuserdb authpam", daemons=5

Aug 18 12:29:23  authdaemond: Installing libauthpam

no me da ninguna pista, alguna idea??
