Recently there's been a new spate of spam reaching ISU Extension mailboxes. Spam blocking and filtering is a battle with escalating tactics. We on the spam fighting side are nearly always on defense and each time spammers find a new strategy, some spam inevitably gets through.
I'm posting the message I sent in email here as well to provide another place with a roundup of links on the nature of spam and what you can do to keep as much of it as possible out of your mailbox.
The first, most important thing to know about spam is this:
--60 billion emails a day
--90% of all emails
That's how much spam is in the network every single day. What this means to you is that you will always get (some) spam. There is always someone looking for a new way to send it, for a new technique to get by spam filters, for a way to worm their way into your mailbox and make you look. If your mailbox on any given day contains less than 90% spam, someone, somewhere is helping you out.
The second important thing to know is that there are some things you can do so that you see less spam.

Note: to turn on Outlook's Junk E-mail filtering as well, go to Actions--Junk E-mail--Junk E-Mail options.
