Relay access denied for incoming mail

I have been reading through the posts and was unable to find a solution to my particular problem. This is what I get when I try to send an email to myself from my indiana.edu address.

Code:

The original message was received at Mon, 22 Jan 2007 08:00:32 -0500 (EST) from stjoseph.uits.indiana.edu [129.79.1.78]

   ----- The following addresses had permanent fatal errors ----- <[email protected]>
    (reason: 554 <[email protected]>: Relay access denied)

   ----- Transcript of session follows ----- ... while talking to mail.scratchco.com.:
>>> DATA
<<< 554 <[email protected]>: Relay access denied
554 5.0.0 Service unavailable
<<< 554 Error: no valid recipients

and this is the log at /var/log/mail.log

Code:

Any help would be appreciated.

Also, in the first log I see someone trying to relay as [email protected]. Does this present a threat?

 

If that is not an account actually on your system, it could be someone trying to use your server for spoofing or using it as an open relay hoping to source spam from your server.

Was the relay attempt denied?
