Exchange 2003 event ID 7002


just had a look at the application log on my mail server today and noticed a bucket load of warnings with an id of 7002

Event Type:      Warning
Event Source:      MSExchangeTransport
Event Category:      SMTP Protocol
Event ID:      7002
Date:            4/8/2011
Time:            8:47:21 AM
User:            N/A
Computer:      BPDM02
This is an SMTP protocol warning log for virtual server ID 1, connection #3438. The remote host "", responded to the SMTP command "rcpt" with "450 4.7.1 Client host rejected: cannot find your hostname, [x.x.x.x]  ". The full command sent was "RCPT TO:<argos@email-argos.co.uk>  ".  This may cause the connection to fail.

I've gone to http://www.abuse.net/relay.html and put in IP (x.x.x.x) and it comes back saying i'm not an open relay. so i assume thas good.

is this just a case of someone trying to use me as an open relay but can't because i'm locked down?

Yes you are right the above event states that someone is trying to use your server as an open relay but can't because serevr is locked down

The above event has recorded because SMTP Diagnostic Logging is Enabled for SMTP protocol ,if you set the SMTP Diagnostics to "NONE" then above event will no more recorded on the server

If you do not want the above events (7002,7010) , simply set the SMTP Diagnostics to "NONE"

Hope this helps.
