One of the most overlooked areas of email security is your own domain reputation. Unlike most email security solutions, Reputation is focused on you as the sender’s ability to send email to recipients and to stop spammers from spoofing you and claiming to send email as your domain.
We have received several reports over the weekend that customers email has been flagged as spam by some receiving mail servers.
Bounce backs included errors such as:

<– 550 Email blocked by bl.spamcop.net (in reply to RCPT TO command)
On closer investigation it appears there was a system outage at the Cisco SpamCop DNS-based blocking service and the underlying cause was that the spamcop.net domain name had failed to be renewed.
