What is SBD spam control?
SBD spam control scans your incoming e-mail to tag annoying and offensive junk mail (spam) before it reaches your mailbox. It is an automatic filtering system that greatly reduces the amount of spam that reaches your Inbox. If an e-mail is determined to be spam, the spam control program identifies the spam to the user by inserting the tag -= spam Detected by Secure by Design =- into the subject line.
