QQQ%%%ZZZ 193.229.31.170 got 10 numbers, 86425 through 86434. Next free is 86435


What site is orbs.dorkslayers.com and why it is considered so spamful?
I think now it would be just enough to swap the To: and Cc:
fields, so that To: would contain the address of the reserver
and Cc: the address of Neil, so there would be only 6 - 1.5 = 4.5 points,
just less than the spam threshold of 5. However, these settings may
vary on other sites. (So maybe also one could use lowercase in the subject,
e.g. something like OEIS: New A-numbers, etc.)


Yours,
