Hello.
You can try adding to your main.conf:
tcp_windowsize=65535
See also:

This won't help.
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

see and report what happens.

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 of

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
