Do you have reason to believe that a configuration that works with Mojave won't work with Catalina?
In the distant past OS upgrades broke my Postfix configuration, but moving to Mojave was seamless.
I'm still on Mojave, so I'm very curious about this.
I’ve had postfix running no problems up to Catalina, but Catalina has broken parts of it and I’m struggling to find out why.
It’s a complex version I’m running, or was running,
Postfix+dovecot+MySQL+ssl and tls + dcim and various spam engines. Etc etc. something in the chain has come unstuck and I’m losing interest in tracing it.
Anyway, I’m thinking of unloading it all entirely and going with a third party mail handler. Or not at all.
So I looked at the Catalina version of Postfix, and can’t find any ... I mean any... documentation on running it.
