Question : SMTP Auth command syntax

I am trying to trouble shoot my exchange 5.5 setup. I need to test whether or not spammers are able to use the AUTH command during a telnet session to port 25 to authenticate a user or the guest account on my server. I do not know the exact syntax for the command or when during the session it needs to be issued.
Thanks for any help.

Answer : SMTP Auth command syntax

Here you go:

telnet server 25
ehlo mydomain
auth gssapi   <  ---- can also be "auth login"
some account based64 encoded
some password base64 encoded
mail from:sender address
rcpt to:recipient address
data
Somedata, yadda yadda yadda
.


Accounts and passwords are base64 encoded.  Here is a link to a base64 encoder:
