Try locally on the mail server but connect to 127.0.0.1
It may be possible that postfix isn't listening on all the IPs... |

A blank screen usually means that Postfix is waiting for something. In the end, it will show a prompt, but that could take minutes, which is too long for many MTA's to actually deliver mail. Most of the time it's DNS, that Postfix is waiting for. On the host, try "host some.remote.host" or "nslookup some.remote.host". If that times out, too... Look at your firewall for outgoing DNS settings.
Also, the /var/log/mail.log or /var/log/maillog (depending on your OS) could show some hints...

It looks like DNS is working properly as near as I can tell. Mail is getting to the server, it's just not getting to any inboxes.
