What I'm not clear about is what happens when the mail is sent onwards
by the 'smarthost' at Gandi. Does it change the envelope sender to
Send an email to yourself and have a look at the headers.
Some MTAs add received headers like "received by for ".

That still doesn't tell you what the effect is of entering a value for that
setting while the traffic is not coming from a proxy. Normally, when you enter
config data
It's practically not possible to support both with and without haproxy

receives plain bytes with the TCP protocol. The interpretation of these
bytes can only be done by defining the protocol underneath. When you set
the protocol t

So, I added this in master.cf:
smtp inet n

Postfix should not simply ignore such errors. How would Postfix
distinguish this from haproxy crashing or

Actually, one postfix is running on Linux and requires lmdb: the other is
running on macOS and requires btree:
This works on Linux:
smtp inet n - n - 1 postscreen
991 inet n - n - 1 postscreen
-o postscreen_upstream_proxy

The premise is the same, craft a PCRE expression that matches what you
