Thanks for reply

I checked your theory right now, and i afraid that it is not as simple, as
i see grow in the first 9 hex numbers, eg. (unique values):
0100018fe...
0100018ff...
010001900...
010001901...
010001902...
Seems to be some sort of counter...
>Also, it's very, very easy to set a custom return-path subdomain in SES.
I afraid, that real spammer will not want to use as easy identifier ;-)
>Mine is customized, as you can see above. Thus you could take the stance
>that you'll block @amazonses.com and anybody who wants to get past that can
I don't want to be as agressive on return-path, it is (can be) shared
and not all people are aware of two "From" in email, but yes, i already
assing high score if that domain appears in MIME From:, but i didn't
remember/notice any yet :-)
