problem in Authentication.

[Rajeev R Veedu]

I have an openexchange setup with Cyrus Imap and SASL authentication. 

 

May 16 11:40:38 mail pop3[7641]: badlogin: [192.168.1.68] plaintext
matthew_sullivan SASL(-13): authentication failure: checkpass failed

May 16 11:40:38 mail pop3[7640]: badlogin: [192.168.1.69] plaintext duncan
SASL(-13): authentication failure: checkpass failed

May 16 11:52:04 mail pop3[7713]: badlogin: [192.168.1.114] plaintext s.kim
SASL(-13): authentication failure: checkpass failed

May 16 11:52:04 mail pop3[7650]: badlogin: [192.168.1.52] plaintext sajiv
SASL(-13): authentication failure: checkpass failed

 

The system was up about 1 year and I never faced this problem. Also I
haven't changed any settings in the configuration. 

 

Since yesterday I am getting this RANDOM authentication failure and would
appreciate if you could help me,

 

Regards
