A message from &lt;mba(a)thebarn.com&gt; to: -> mba(a)thestof.com was considered unsolicited bulk e-mail (UBE). Our internal reference code for your message is 06875-02/Rv6ZIS-5eKEn 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.
