Re: Exch2k3 drops remote connection attempts

That's right, and in this case it is not the problem. from the internal
network telnet is working as it should be. If you connect from the internet
to the smtp port (25) than the server drops the connection.

Seems there is something wrong on the level of:
- SMTP server / service
- Exchange SMTP connector
- Exchange server
- Routing and remote access
- network adapters
- routing

I'm all out of options right now. Any ideas where to find this mysterious
block, which is preventing all external mail from being delivered where it
should be.
