Hello,
In the xxx_tls_level section:
Postfix version 3.11 changes the default value for client TLS security
levels from "empty" to "yes".
Should be if I am not mistaken:
Postfix version 3.11 changes the default value for client TLS security
levels from "empty" to "may".
Regards,
Emmanuel.

I received an email sent via HubSpot. It has two DKIM signatures.
Postfix shows this:
Authentication-Results: DOMAIN1;

Bounces are sent with the null envelope.from address which has no
domain. Therefore, SPF applies policy to a surrogate: the hostname
in the SMTP client's HELO/EHLO command (as if the envelope.from
address was postmaster@helo-argumen
defined in single-wild.porcupine.org zone.
Thus, when A record for mail01-t122.raystedman.org already exists,
the *.raystedman.org TXT record will not cover it and explicit TXT
for mail01-t122.raystedman.org must be created (I see it's been done)

Thank you again for your feedback on this issue.
I watched the workload in real time this morning and now have more
insight into what is happening. It appears the large ISPs are using
TLS connection as a way to throttle incoming traff

Emmanuel,

That's crazy, If you're able to run a dedicated proxy instance, you're able to
run an outboud postfix instance too: the perfect proxy software for

Obviously, nginx will not know the Postfix SMTP client protocol stage, and the
nginx settings will have to match the largest
Postfix timeouts to avoid persistent mail delivery problems with some sites.

You can dig the UTF8 hostname, they are valid for query.
