| Apparently a number of spammers have figured out that sending emails with nothing in the "Subject" box/line will confuse many email program's filtering (especially anything from Microsoft, can't say for sure on Thunderbird or other 3rd party software). But there is a way around this.
You can create a mail rule that will send any email with no Subject to a junk or deleted folder. Here's how:
An Outlook Rule for Messages with No Subject
This should work in Outlook Express, Outlook, and Windows Live Mail.
PS: in addition to all the vowels you may want to add "f" or "fw" for those occasions someone forwards you an email without anything else other than FW in the subject box/line.
