[user1378]

hello every1,
i am installing an new open-xchange-server (7.8.1) on debian 8 and created a few contexts and users. users could login. but i forgot to set the right loginsource for the sieve-server. after changing the loginsource in mailfilter.properties i restarting the open-xchange service.

after that i can't login anymore.

Der Server wird derzeit gewartet. Bitte versuchen Sie es später erneut. (CTX-0007)
