Hi,
Depending on your client / server interaction, you might be able to setup an
ssh tunnel or a wireguard vpn between client and server, then use localhost:587
for submission, bypassing Crunchbits' firewall.
I see no other reliable way to do it (other than changing providers).

Any sign of postfix 3.9 blacklisting HAproxy because of SMTP

I’m using openarc from https://github.com/trusteddomainproject/OpenARC
May be dead but does work.
You could try https://github.com/fastmail/authentication_milter

OK. I’m still running 1.10 : it does not use a config file. Configuration is
only in /etc/rc.conf.
It’s normal that config files for 2.0.8 are new and not tunned.

Hello,
You will find bellow parts of my script that create a virtual alias map from on
premise AD. You’ll have to work on transforming the output yourself
(/usr/local/bin/get_exchg_aliases.awk in my script).
And you’ll have to tune AD_FILTRE to suit your needs.

Hello,
I’m surprised to see that dnsblog can issue up to 40 absolutely identical DNS
requests per seconds, for postscreen, when my setup reads:
