And please see the following defaults,
root@mail:~# postconf -d smtp_use_tls
smtp_use_tls = no
root@mail:~# postconf -d smtp_tls_security_level
smtp_tls_security_level =
under these defaults, I am afraid if I don't setup them, postfix will
always talk to peer with plaintext, even peer supports
Most hosting providers block outbound traffic to port 25 by default. A
simple telnet to outside port 25 can verify it quickly.

We have no way to help you on this. The reason is only known by MS itself.
If I was you, I will check the following stuff on my end,
1. sender IP reputation (listed in any RBL?)

I saw 96-92-246-116-static.hfc.comcastbusiness.net has no A record pointing to
your IP.
Though this IP does have a PTR record as above.
Maybe you have 'reject_unknown_client_hostname' setup in your main.cf?
Thanks.

Hello
I have a question about forwarding email to Gmail. Gmail requires the
sender to provide identity authentication, including SPF or DKIM. Some
of our old customers do not have dkim configured in their email system,

Great examples. Thanks for pointing out that.

what's the main difference between a policy server and a milter?
I searched and found this link:

Because I am using the VM, and my VM provider doesn't have ubuntu 24.04 available.
maybe I should try to get a ubuntu 24.04 from another provider and install the postfix 3.9 package then.
Thanks for all help.

Ill be honest.
Hello community,
Rather than compiling from the source, do you know if there is another better way to install postfix 3.9 on ubuntu 20.04 system?
I google it and found nothing useful thought.
Thanks.
