  • help i think i'm opened to mail relay and problem with SMTP commands

    Hi,

    i've a server that suddenly have an SMTP problem.
    first i see in the mailroot queue that i've 5700 emails,i've stop the smtp service and delete all the messages in there,then i've set only the server in the smtp relay connection and authenticated users only submit to the server.emails are going out and recive good.
    but when i try to make a "telnet servername 25" i get this banner
    "220 ************************************************** ***********0****0*2*************************200*** ***0*****0200"
    and the server dosen't answer to smtp commands like helo,mail from:,and so on.
    why is that?

    Thx

    That is a Cisco PIX getting in the way. Disable fixup SMTP in the PIX configuration and you will then see the Exchange server respond.
