Hallo Liste, Google blockt in letzter Zeit Mails von meinem Server an Gmail Accounts.
***@gmail.com: host gmail-smtp-in.l.google.com[2a00:1450:400c:c09::1b] said: 550-5.7.1 [2a01:4f8:c17:12f8::2 12] Our system has detected that this 550-5.7.1 message is likely unsolicited mail. To reduce the amount of spam sent 550-5.7.1 to Gmail, this message has been blocked. Please visit 550-5.7.1 https://support.google.com/mail/?p=UnsolicitedMessageError 550 5.7.1 for more information. q9si858297wmf.73 - gsmtp (in reply to end of DATA command)
Hat jemand eine Idee was die da prüfen um zu dem Ergebnis zu kommen?
Jochen
