To filter based on these headers, you will need to configure filtering
Phishing email messages, and websites, are designed to steal information from you (e.g. account information, personal information, etc).
If you see a link in a suspicious email message, don't click on it. Rest your mouse (but don't click) on the link to see if the address matches the link that was typed in the message.

You may tweak the settings of SpamAssassin by editing a file in your home directory called ~/.spamassassin/user_prefs. If you find that email from Alice is being filtered incorrectly (you wish to receive email from this address), you may whitelist the addess in this file. If you find that email from Bob is not being filtered (you do not wish to receive email from this address), you may blacklist the address. Example:
whitelist_from alice@*ias.edu blacklist_from bob@*ias.edu
The "*" in the address is a wildcard, you may whitelist an entire domain by using wildcards, to whitelist all of gmail, you would put whitelist_from *gmail.com in your user_prefs.
You may train the Bayes filter on SpamAssassin by placing any SPAM that arrives in your INBOX into the folder "Spam" in your Mail directory. To properly train the filter you will also need to copy good email or "Ham" into the folder called "Ham" in your Mail directory. Email placed in either of these folders is automatically deleted after being added to the Bayes filter. These folders may not already exist in your account, you can create them through pine or Thunderbird. Please use the names "Ham" and "Spam" with the same capitalization.
