I have set up a postfix server with amavis content filter. Some people that sends mail to me gets the following in return, what does it mean? Emne: Considered UNSOLICITED BULK EMAIL, apparently from you A message from <Bev*@*.no> to: -> post@*.no was considered unsolicited bulk e-mail (UBE). Our internal reference code for your message is 13958-03/Un-4ymmXJAzg The message carried your return address, so it was either a genuine mail from you, or a sender address was faked and your e-mail address abused by third party, in which case we apologize for undesired notification. We do try to minimize backscatter for more prominent cases of UBE and for infected mail, but for less obvious cases of UBE some balance between losing genuine mail and sending undesired backscatter is sought, and there can be some collateral damage on both sides. First upstream SMTP client IP address: [193.213.*.*] mail48.*.no According to a 'Received:' trace, the message originated at: [83.109.*], brbar (ti221110a080-*.bb.*.no [83.109.*.*]) Return-Path: <Bev*@*.no> Message-ID: <6D188882CC5D405AA1A9*@brbar> Subject: ny test Delivery of the email was stopped!
