Junk Mail -- What can I do?

We all get emails from people we don't know (spam) and how can we handle these? GroupWise has a couple of things each individual user can do to block emails from coming into their mailbox. PTS does run a "Spam Blocker" on the overall site, but hey spammers are good. They have started mocking school sites (notice that the addresses look like school addresses .k12.oh.us). Here's some steps you can take:

1. You can add individual e-mail addresses or entire Internet domains to a Block List. Items from these addresses or Internet domains are blocked and never arrive in your Mailbox.An Internet domain is the part of the e-mail address that comes after the @. For example, in the address Henry@mymail.com, the Internet domain is mymail.com.
2. You can add individual e-mail addresses or entire Internet domains to a Junk List. Items from these addresses or Internet domains are delivered to the Junk Mail folder in your Mailbox. You can specify that the items in this folder be automatically deleted after xx days.
3. You can specify that any e-mail items from users whose addresses are not in your personal address books (including your Frequent Contacts address book and any personal address books you have created) are sent to the Junk Mail folder.
4. In your GroupWise Inbox, right-click an item with an Internet address; click Junk Mail.
5. Click Junk Sender OR Click Block Sender.
6. Select Junk E-Mail From This Address or Block E-Mail From This Address. If you select Junk, the address is added to the Junk List. All future e-mail items from this e-mail address will be delivered to the Junk Mail folder. You can specify that the items in this folder be automatically deleted after so many days. This folder is not created in the folder list unless a Junk Mail option is enabled or an address or Internet domain is added to the Junk List (which enables the Junk List option). If you select Block, the address is added to the Block List. All future e-mail items from this e-mail address will not be delivered to your Mailbox.
7. If the Junk List or Block List is not enabled, select Enable Junk List or Enable Block List.
   At any time, you can click Tools > Junk Mail Handling > Junk List or Block List > New to add an e-mail address to the Junk List or Block List.
