Within WebMail there is a number of Spam Control options available.

1.	Friends - automatically stores email from unknown senders in your 'pending' folder awaiting a reply to a confirmation message. This helps check they are a real person and not just a spam program.
2.	Spam Filtering - automatically stores email that is suspected to be spam in your 'held' folder for 2 weeks. You can go to your 'held' folder to release messages wrongly identified as spam.
3.	SPF filtering - This blocks most spam by rejecting emails where the sending machine is not the mail server for the domain used in the from address

We recommend users control spam by setting

1.	Friends - On
2.	SPF filtering - on or Spam Filtering - on
