PST Files - corrupt files and lost password - pst19upg.exe - run multiple times.
A size limit of 2GB (1.8 to be safe) is applied to ANSI format .PST files.  Outlook 2003 has the ability to create UNICODE format .PST files which have a "safety" cap of 20gb.  ANSI .PST files are not automatically upgraded to UNICODE when upgrading to Outlook 2003.  You must create a new UNICODE .PST and move your objects into it.  (Thanks to Micheal Espinola Jr)

Junk e-mail is called Spam or UBE (Unsolicited Bulk Email).  If you only get a few (10 a day) then just delete them.  My personal e-mail generally gets 100 spams per weekday and about 300 on the weekend.  Monday morning there were generally 350 or more junk emails, and about 10 real ones.

For my personal POP3 e-mail, I have moved to a Bayesian filter based on Paul Graham's A Plan for Spam.  Bayesian filtering analyzes each word in the e-mail and assigns a "spamminess" to the message.  You train it on your e-mail, which is unique to you.  That's why it's so accurate.  I use Robin Keir's K9 and it automatically moves the spam (with a 99%+ accuracy) to a different folder than my inbox.  This software gave me back my email address.  This program has got to be one of my all-time favorites - its's easy to setup, is supported by newsgroups and it's accurate.  Robin also programmed another one of my favorites SuperScan, look in the Links section.

From 3/11/05 to 5/17/05, I ran an extensive test of K9.  During this run I received 6,907 emails.  For detailed stats of this, click here.

GMail http://www.gmail.com  I have been using a Gmail account since mid 2004.  I really like it and it has a pretty fair spam feature.  I don't know how it's implemented, but its pretty accurate.

Norton Internet Security has some spam features, I've heard that it works well, but I have not tried it.

POPFile (free), http://sourceforge.net/projects/popfile/ Bayesian spam filter. Highly reviewed, I tried it in 2001 and it was OK.  I think it has been updated quite a bit since then.

Don't reply to e-mail asking for personal information.  Most legitimate companies will not ask for personal information by e-mail.  If it seems like a company you trust, such as your credit card company, is writing to ask for personal information, call them and report it-do not respond to the e-mail.  Be sure to use a number you found yourself, either through the yellow pages, a bank statement, a bill, or other source-don't use a phone number provided on the e-mail.  If it's a legitimate request, the phone operator should be able to help you.

Tip: Watch out for fake phishing e-mails and spoofed Web sites.  These may appear to come from or represent legitimate companies or popular web sites, however, they are fraudulent copies.  These spoofed mails may be used to trick you into downloading a virus or sending personal information, such as a credit card number.  When in doubt, contact the company you think sent the e-mail.

Don't buy anything from a spam mail.  Some spammers make their living on people's purchases of their offerings.  So resist the temptation to buy their products if you don't want to take the chance of getting on more junk e-mail address lists.

Never contribute to a charity from spam mail.  Unfortunately, some spammers prey on your good will.  If you receive an appeal from a charity, treat it as spam.  If it is a charity you would like to support, call them and find out how you can make a contribution.  But don't send your information by e-mail.

Think twice before opening attachments, even if you know the sender.  If you cannot confirm with the sender that a message is valid and that an attachment is safe, delete the message immediately, and run up-to-date antivirus software to check your computer for viruses.

Don't forward chain e-mail messages.  Chain mails may be hoaxes or even a virus delivery system.  Plus, you lose control over who sees your e-mail address.  Additionally, there are reports that spammers use chain letters to gather e-mail addresses.  To check on the legitimacy of a chain letter or potential hoax, go to Hoax busters. http://hoaxbusters.ciac.org/
