Dear, I'm in Internet and testing if my mail server is an Open
Relay. So I execute:

telnet mail.mycompany.com 25

After that I do:

mail from: us...@mycompany.com
OK
rcpt to: us...@mycompany.com
OK
data
This is a test !!!
.
QUEUED

The mail from user1 to user2 (both from my company) was sent
OK !!!

Is this behavior normal or is it an open relay ??? Can I sent
a message from one local user to another local user, being
that I come from Internet and not from LAN ???

Thanks a lot

A.F.



Yes, that's normal. "Open relay" means the RCPT can be an unrelated domain eg. @hotmail.com.
