I have a setup with Cyrus Imap and SASL authentication. + Postfix I am getting following error on maillog.
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
Rajeev
