My emails to Cisco people are now bouncing. It seems the cause is a poor rep on one of our MTAs: http://www.senderbase.org/lookup/?search_string=2001%3A630%3Ad0%3Af102%3A%3A25e The DNS reverse seems fine for falcon.ecs.soton.ac.uk
But the email bounce (with username deleted) says: Final-Recipient: RFC822; [email protected] Action: failed Status: 5.1.1 Remote-MTA: DNS; alln-mx-01.cisco.com Diagnostic-Code: SMTP; 550 Connections from the host falcon.ecs.soton.ac.uk (2001:630:d0:f102::25e), originating from SenderBase Network Owner ID: None, are being rejected due to a low SenderBase Reputation Score. See http://www.senderbase.org for more information or contact your IT support team. If any Cisco people are on this list, please have someone have a look. I think Andrew Yourtchenko is, and he is one person with bounces. Tim
