Richard,
<br />
<br />It looks like someone is trying to break into your system with the generic username "webmaster". Be thankful that you are getting those messages - it means the scum didn't get in.
<br />
<br />Actually, since that was saslauthd - they're trying to relay e-mail through your server (probably SPAM). Check with the owner of that domain - to see if they've got a new user named "webmaster" that might be trying to send e-mail. They're probably not correctly configured for SMTP Auth, and its causing the errors.
<br />
<br />Or just ignore it. Nothing hurt, since they're not able to relay....
<br />
<br />
<br />
<br />Chuck
