Sure. Just tell postmaster@freebsd.org *what* address mpcustomer.com is subscribed as. Hint: it's nothing to do with mpcustomer.com -- that was the first thing checked. Now, in order to work out how mpcustomer.com is subscribed to this list, the obvious thing to do is examine the headers of any list e-mail as received at their help system. Or examining mpcustomer.com's mail logs to correlate the incoming e-mails with the host(s) relaying them. That involves mpcustomer.com spending some time and effort investigating, and that seems to be something they are not doing. Not a good advert for them, but they don't seem at all bothered by any potential loss of reputation. The only other mechanism might be to tag each list e-mail with a unique value for each recipient in such a way that it is preserved in the message that mpcustomer.com's help system sends out. That has severe problems of scale and load on the FreeBSD mail servers, but it might be possible. There is a similar technique (whose name I have temporarily forgotten) that some mailing lists use where they tag the envelope sender address with the recipient name in order to identify addresses that are bouncing back the list e-mail.
