Dear all,

I have problem as below:
Type: Warning
Source: Smtpsvc
Event ID: 4000
Description:
Message delivery to the remote domain DomainName failed.
The connection was dropped by the remote host.

Based on the information in
http://support.microsoft.com/default.aspx?scid=kb;en-
us;286673

I need to install MetaEdit2.2, i follow all the
instruction.
Now I can't find SmtpInboundCommandSupportOptions to turn
off my 8bitmime ESMTP???

Please help, if anyone know the solution.
