ca.gov email servers under spam attack
For the past couple of days many ca.gov domains have been under attack with a huge volume of spam. The result is effectively a denial of service of the mail servers, as they are saturated with connection attempts. This has caused various many emails to sporadically bounce because the sending SMTP mail servers are unable to connect to the ca.gov mail servers.
Using an inbound hosted mail filtering service such as Postini or MxLogic can help avoid this problem for your organization because they host multiple inbound SMTP servers, and have a focus on the stability and reliability of these services so you don’t have to worry about it.
