Hi Guys,
I hope someone can give me some advice how to figure out this problem:
I've got a Mavericks Server running and one particular user is getting blocked out almost immediately .
Situation as follows User is getting blocked after ~5 min
-Server is set to 10 attempts before blocking a user
-Mail Server log showing is showing a login attempt every ~ 30 seconds with wrong pw from the Servers local IP
-Roundcube is in use as webmail
Has anybody an idea how to figure out which app is trying to connect? I've checked all obvious things like Mail app iPad iPhone etc also I've checked all other tools in use on the Server itself but no chance of finding the issue even after deleting the user it still tries to login.
Logs giving errors like :
Dec 11 18:40:39 auth: Error: od[getpwnam_ext](USERNAME,IP,<1pyEHPUJAgBRrogM>): No record for user
or
Dec 10 08:40:43 imap-login: Info: Disconnected (auth failed, 2 attempts in 8 secs): user=<USERNAME>, method=PLAIN, rip=EXTERNAL IP, lip=INTERNAL IP, TLS
