    Hello,
    I can detect that with Plesk 8.0.1 is possible send infinite BAD commands and Qmail never close the connection. It's a serious problem for us.

    Does someone have any idea how stop "unrecognized commands" with count_unrecognized_commands?

    Example:
    telnet myplesk8.com 25
    wrong command1
    502 unimplemented <#5.5.1>
    wrong command2
    502 unimplemented <#5.5.1>
    wrong command3
    502 unimplemented <#5.5.1>
    wrong command4
    502 unimplemented <#5.5.1>
    wrong command5
    502 unimplemented <#5.5.1>
    wrong command6
    502 unimplemented <#5.5.1>
    ... infinite ...

    Now, How is possible to stop this? Maximun 10 wrong commands for example is a good value.

    Other question:
    I cann't send message to mail.mides.gub.uy, always appear this:
    Hi. This is the qmail-send program at
    I'm afraid I wasn't able to deliver your message to the following addresses.
    This is a permanent error; I've given up. Sorry it didn't work out.

    <gbarce@mides.gub.uy>:
    Sorry, I wasn't able to establish an SMTP connection. (#4.4.1)
    I'm not going to try again; this message has been in the queue too long.

    But this problem only appear with qmail.

    Can you help me with a simple test on telnet (inside one linux server with qmail)?

    On my server appear:
    But since, my pc Windows, I don't have any trouble :confused:

    Thanks a lot!

    pisha, en los servidores de correos serios (Postfix) gracias a dios se puede poner a cero fallos si quieres, es más uno es suficiente, puesto que un servidor de correos no se equivoca cuando se comunica con el tuyo para enviarle un correo, y asi te quitas millon de posibles programas de envio masivo de correos.
