Hallo Liste,
heute ist mir in meinen Logs folgendes aufgefallen:
Jun 24 11:55:37 winnetou postfix/smtpd[24567]: initializing the server-side TLS engine Jun 24 11:55:37 winnetou postfix/smtpd[24567]: connect from mailout06.t-online.de[194.25.134.19] Jun 24 11:55:38 winnetou postfix/smtpd[24567]: NOQUEUE: reject: RCPT from mailout06.t-online.de[194.25.134.19]: 554 5.7.1 Service unavailable; Client host [194.25.134.19] blocked using dnsbl.sorbs.net; Currently Sending Spam See: http://www.sorbs.net/lookup.shtml?194.25.134.19; from=rechnungonline1@telekom.de to=tobias@koopmann-mail.de proto=ESMTP helo=<mailout06.t-online.de> Jun 24 11:55:38 winnetou postfix/smtpd[24567]: disconnect from mailout06.t-online.de[194.25.134.19]
Warum ist die Telekom hier gelistet und hat heute noch jemand sowas beobachtet?
Vielleicht ist auch was an meiner Config bröselig?!, häng sie einfach mal an:
