Subject: Considered UNSOLICITED BULK EMAIL, apparently from you

A message from < me@domain.com> to:
->  origen@serverdomain.com

was considered unsolicited bulk e-mail (UBE).

Our internal reference code for your message is 26136-16/WL-CfZErXhzU

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.
