As some of the private response (and half the time, their tone) suggest... I am indeed a masochist. However, two useful details have been exchanged that at least clarify some possibilities: 1. It appears my IPv6 address for my new server instance has been swept up into a spamhaus PBL entry. This wasn't the case during initial setup and prior rounds of triage, but it'll certainly cause issues now. 2. It appears the provider I'm attempting to use, Hostinger, has made it onto sufficient other hidden black lists that the address ranges are problematic. So, the issues are not configuration, they're collateral damage, and there's diddly squat I'll be able to do about the issue aside from "move somewhere more reputable". Unfortunately, good luck finding "somewhere more reputable". Note that suggestions for hosted mail accounts aren't helpful for me at the moment. The property I'm trying to preserve is a number of customizations to my mail routing that rely on running my own postfix instance. -- Jeff
