AOL's redaction is both overkill and ineffective if you use VERP. I.e,
with VERP, the envelope is from
LISTNAME-bounces+screenname=aol.com at your.host. This appears in a Sender:
and Errors-To: header and the delivery agent's Return-Path: header. In
all three cases, AOL 'redacts' this by changing
LISTNAME-bounces+screenname=aol.com at your.host to
redacted-bounces+screenname=aol.com at your.host. Here are partial headers
from an AOL feedback report. All addresses are unchanged from AOL's
report except I changed the AOL screen name in the VERPed headers to
xxxxx, and deleted the From: address.
