SMTP and Qmail count_unrecognized_commands

[crnunez]

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:

[root@ns control]# telnet mail.mides.gub.uy 25
Trying 200.40.188.150...
telnet: connect to address 200.40.188.150: Connection timed out
telnet: Unable to connect to remote host: Connection timed out
[root@ns control]#

But since, my pc Windows, I don't have any trouble

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.
