Will spamBlocker intercept any important messages from EarthLink?
No. Certain email messages will always appear in your Inbox, regardless of your spamBlocker settings. These include Allowed Sender Requests and summaries sent by spamBlocker; most “bounced” email notices generated when you send messages to invalid email addresses; and messages from EarthLink regarding your account, Customer Support, and EarthLink products and services (you can stop receiving messages about products and services by following the unsubscribe instructions in those emails).
