A message from <umfragen(a)fim.uni-mannheim.de> to: umfragen(a)fim.uni-mannheim.de was considered unsolicited bulk e-mail (UBE). Our internal reference code for your message is 29102-18/1oGLLgmWGez4 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 some balance between losing genuine mail and sending undesired backscatter is sought, and there can be some collateral damage on either side.
