Something strange are happening with my new exchange 2000 configuration.
Several domains send us email Ok, for example: @hotmail.com works OK, but some cannot send us emails, and receive the message: " said: 500 5.3.3 Unrecognized command".
I think that it could be a new configuration in E2K, since in our other machine with E5.5 it doesn't happen.
Anyone know what should I do to accept all conections?
Any idea?
