Sorry for double post about my e-mail problem. When I hit send, this crap
e-mail service returned me to its FQDN landing page and I thought I lost my
e-mail, so I logged in and wrote it all again. This time it sent, and then I
returned to my inbox to find replies to the e-mail that appeared not

Hello
So I have a problem sending and receiving e-mail from some people.
The problem I have sending e-mail to some people is that Postfix says the
connection times out when attempting to connect to the server.
This is my setup:

This is typical networking issues.
Nothing about postfix.

So I have a bizarre problem. I can't send e-mail to some servers but I can to
others. The e-mail that doesn't get sent is due to the connection timing out to
the remote server.
Another strange problem is that some people can e-mail me while others can't.
This is how my e-mail server is setup

Then, do continue to provide all essential *FURTHER* commands via telnet and
see and report what happens.

When I open a raw socket to the remote server on port 25 using telnet, I am
able to connect and see the server announce itself, so, it is reasonable to
assume that Postfix is doing the same and timing out during the SMTP
transaction because Postfix is not having a problem sending mail to other

This won't help.
Hello.
You can try adding to your main.conf:
tcp_windowsize=65535
See also:
https://www.postfix.org/postconf.5.html
That can help fixing broken window sizes because of a firewall.
Thanks

network firewall at your or recipients' side.
Routing problems can cause this
