Hallo, ich weiss noch nicht, ob das ein Problem ist... Alle paar Tage hab ich eine Reihe von Warnungen in meinem Log, das sieht dann im Log so aus: Feb 23 03:21:07 mcgregor postfix/smtpd[24506]: warning: 91.207.6.58: hostname 58.6.207.91.unknown.steephost.net verification failed: nodename nor servname provided, or not known Feb 23 03:21:07 mcgregor postfix/smtpd[24506]: connect from unknown[91.207.6.58] Feb 23 03:21:09 mcgregor postfix/smtpd[24506]: error: Unable to lookup user record Feb 23 03:21:10: --- last message repeated 1 time --- Feb 23 03:21:09 mcgregor postfix/smtpd[24506]: error: Authentication failed Feb 23 03:21:09 mcgregor postfix/smtpd[24506]: warning: unknown[91.207.6.58]: SASL LOGIN authentication failed Feb 23 03:21:10 mcgregor postfix/smtpd[24506]: error: Unable to lookup user record Feb 23 03:21:11: --- last message repeated 1 time --- Feb 23 03:21:10 mcgregor postfix/smtpd[24506]: error: Authentication failed Feb 23 03:21:10 mcgregor postfix/smtpd[24506]: warning: unknown[91.207.6.58]: SASL LOGIN authentication failed Feb 23 03:21:11 mcgregor postfix/smtpd[24506]: error: Unable to lookup user record Feb 23 03:21:13: --- last message repeated 1 time --- Feb 23 03:21:11 mcgregor postfix/smtpd[24506]: error: Authentication failed Feb 23 03:21:11 mcgregor postfix/smtpd[24506]: warning: unknown[91.207.6.58]: SASL LOGIN authentication failed Feb 23 03:21:13 mcgregor postfix/smtpd[24506]: error: Unable to lookup user record Feb 23 03:21:14: --- last message repeated 1 time --- Feb 23 03:21:13 mcgregor postfix/smtpd[24506]: error: Authentication failed Feb 23 03:21:13 mcgregor postfix/smtpd[24506]: warning: unknown[91.207.6.58]: SASL LOGIN authentication failed Feb 23 03:21:14 mcgregor postfix/smtpd[24506]: error: Unable to lookup user record Feb 23 03:21:14 mcgregor postfix/smtpd[24506]: fatal: too many errors - program terminated Feb 23 03:21:15 mcgregor postfix/master[514]: warning: process /usr/libexec/postfix/smtpd pid 24506 exit status 1 Feb 23 03:21:15 mcgregor postfix/master[514]: warning: /usr/libexec/postfix/smtpd: bad command startup -- throttling
