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 <br><br><br><b><span style='font-size:10.0pt'>---------- Original Message -----------</span></b><span style='font-size:10.0pt'> <br>From: "Richard Sidlin" <<a href="mailto:richard@sidlin.co.uk">richard@sidlin.co.uk</a>> <br>To: <<a href="mailto:blueonyx@mail.blueonyor%20%0b%0b%0bx.it">blueonyx@mail.blueonyor <br><br><br>x.it</a>> <br>Sent: Mon, 7 Jul 2014 18:51:50 +0100 <br>Subject: [BlueOnyx:15623] Saslauthd Errors <br><br>> Hi <br>> <br>> These errors keep popping up every few minutes.
