   Also check the IPs of your neighbours (in the same subnet or network block). I suspect the big ISPs also look at this, and on Hetzner at least I've found many neighbours with somewhat spammy IPs.

   I'm doing it, also using Qmail. I've felt the same pains as you (even started to suspect that providers might detect mail was being sent by Qmail and scoring that lower (perhaps (only) spammers are using Qmail today?), but more pr

   But then read-only just means unmodifiable ? How does it matter whether it's a lookup table or CPU code in ROM or whatever? And the OP said "mathematically unhackable", not unmodifiable. But for me it seems completely in the
