We have a lot of emails bouncing back and I think the reason why is because our exchange server name is VISTA_2003 I think the ISPs are rejecting the _ but need to confirm this is the error before taking action?

Event codes below:

Event Type: Error
Event Source: MSExchangeTransport
Event Category: SMTP Protocol
Event ID: 7004
Date: 17/05/2007
Time: 16:12:35
User: N/A
Computer: VISTA_2003
Description:
This is an SMTP protocol error log for virtual server ID 1, connection #7186. The remote host "Syntactically", responded to the SMTP command "helo" with "501 Syntactically invalid HELO argument(s) ". The full command sent was "HELO VISTA_2003 ". This will probably cause the connection to fail.
