Hello,
Few days ago I've stumbled on this gem:
https://twitter.com/gabsmashh/status/1542154330836553728
This is why I can't work in a normal organization...
I don't think I could survive being required to respond to such an
assertion.
It made me wonder about headers manipulation so I have few questions:
- are you aware of email servers that can/will manipulate headers so
that recipients order is altered?
No.
I mean, not any pure MTA. It might be done in integrated mail systems
like CommuniGatePro or Zimbra, where a web MUA interface is used to
compose mail, but even there it would be incidental to constructing
headers initially, not an intentional reordering.
One could implement this in a milter, of course, and I've even written
code for a MIMEDefang installation that takes care to NOT reorder
addresses in address list headers when normalizing them (to avoid having
Sendmail 'fix' them after signing.)
- would it be possible to randomize recipients order with some header
rewrite in Postfix?
Not directly in Postfix. Wietse is not actively and intentionally evil.
