So, first of all, thank you all for the input, suggestions, and help -

After much toing-and-froing I finally tracked down the issue, and I'm

I'm not sure how to go about doing this (what I'm about to describe

As I said, I didn't know if it was a Postfix, TLS Cert, or MariaDB

Hi All,
When using `postscreen_upstream_proxy_protocol = haproxy` is there
anything "special" that needs to be specified to ensure the use of v2 of
the haproxy protocol, or does postfix automatically detect which version
of the haproxy protocol is in use? The doco isn't clear (to me, anyway).

Is this actually good advice, or is there some sort of "gotcha" hiding
