Sorry for the interruption of postfix technical discussions.
I cannot reach the www.postfix.org server. I have to use a mirror if I
want to get to the documentation.
I've found using host and dig that www.postfix.org is a cname for
postfix-mirror.horus-it.com (65.108.3.114). That mirror is
.hetzner.com (213.239.252.198) 151.152 ms
150.267 ms 150.374 ms

never get to ra.horus-it.com (65.108.3.114).

Maybe some routing issues of your upstream provider?

Correction: I was only trying to connect using https or http.

Thanks. Got the same result.
I get a reply from the server just upstream from the host but not the host.

There are currently no existing blocks in the 47.201.
I can't ping it.

My mistake about Germany. I was going by the whois info for hetzner.com

My fault.
I was looking for reasons in my Ubiquity router's configuration and
found that Ubiquity had added a filter for TOR exit sites in an update
and it was enabled by default. Of course the setting is buried and a
search does not bring up the setting. Why it is being triggered and
I was running traceroute as root.

I configured DNSSEC to handle the domains that were failing lookup.
Anyway, thanks to all.

Found the issue.
As Wietse said, the resolver (bind) was bouncing emails from hosts that failed
DNSSEC.
Some domains are using an old algorithm that is no longer accepted by the
current DNSSEC default configuration. Three I have found are:
comcast.net (algorithm 5), medicare.gov (algorithm 7),
I just spent 1 1/2 hours on a chat with my ISP "tech support." What a
waste of time.
{rant] All I wanted them to do was open a web browser and try and reach
the site from inside the Frontier network. They either couldn't or
wouldn't. I even mentioned that the site was a TOR inner node. I don'
I set the values in main.cf:
# postconf -n | grep -P '_reject_code = \d\d\d$'
plaintext_reject_code = 550
unknown_address_reject_code = 550
unknown_client_reject_code = 550
unknown_hostname_reject_code = 550
unknown_local_recipient_reject_code = 550
unverified_recipient_reject_code = 550

How about a port forward rule in the NAT router?
25587 -> host:587
That way the host gets gets the traffic on a port it understands.

Thank you.
Very clear.
I will look further than the file header for information in the future.

What is the difference between listing host in virtual vs mydestination in
main.cf?
Is there an advantage to one over the other?
I read the header for virtual and don't really understand the difference.
