In
the Spam Filters area you can create simple to complex filters for your email.
Functionality includes filters based on the To:, From:, Subject:,
and Body: of the incoming email. These can then be set to "allow"
or "Deny." For example, you could filter all incoming messages with
the word "apple" in the To: line, unless it was sent from contact
named "Mom." This filtering is done only after the message is received
by the server whereas the Domain Blocking feature blocks messages from certain
senders before the message is received into the account (Account Owner and Users).
