I have problems with my postfix service, e-mails are coming back with the following message: A message from <[email protected]> to: -> [email protected] -> [email protected] was considered unsolicited bulk e-mail (UBE). Our internal reference code for your message is 07377-04/KhHNs92MsYNQ 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. Return-Path: <[email protected]> Message-ID: <!~!UENERkVCMDkAAQACAAAAAAAAAAAAAAAAABgAAAAAAAAA5LZ/MIRQVEOR/3UPY8QR/sKAAAAQ [email protected]> Subject: RE: ROMERO Delivery of the email was stopped! Can somebody help my Many thanks
Backscatter, or you need to tighten up your postfix setup or ignore them. I'ts just spammers using you as From and To (+ other To's), and send them with MTA's that don't check SPF/Dkim/domainkeys etc ..
