Stop Spam – 3 Filters I Use In Outlook
Controlling my own domain names puts me in an interesting position. All the spam coming into these domain names becomes my personal responsibility, and I learned early on that the default cpanel spam filters generate more than their proportion of false positives. Prior to getting spamwasher to guard my e-mail I had to manually create filters in outlook to deal with the majority of spam.
As the number of these filters grew I realized I needed a more serious weapon to fight with spam, but if you aren’t quite ready to shell out money just however, or if you’d prefer combat spam with the resources already at your disposal, then the important thing to do is create filters that catch spam, AND ONLY spam. Here’ are some of the best ones I used:
Apply this rule after the message arrives
Where the Subject line contains ‘SPAM’ or ‘failure notice’ or ‘delivery failed’ or ‘undeliverable’ or ‘(Failure)’ or ‘Undelivered Mail’ or ‘Returned Mail: see transcript’ Delete it
This one was additional after I went by an incredible phase of having mail getting bounced back to me. The spammer theory here is a returned message will automatically improving most spam filters, so they send messages to dead addresses using your email address as the reply-to address. When the mail server bounces the message it comes straight by your filters and back to you.
Apply this rule after the message arrives – where the From line contains ‘@olympic.webitdomainz.com’ delete it
This one is fairly specific to me, but is interesting to anyone who uses form-mail. My first attempt at allowing people to contact me directly from the webpage resulted in a mass of spam from spammers exploiting sendmail flaws. Basically they would send spam automatically by my webmail form. As they never filled in a mail address it would appear to come from my old great number(incidentally if you are thinking of hosting with these guys – DON’T).
Apply this rule after the message arrives –
where the Subject line contains ‘STOPSPAMNOW’ move it to the STOPSPAMNOW folder
I wasn’t sure whether or not to add this one as it does give spammers a little window to attack me with. However it is a good example of how to ‘whitelist’ a message. You can use a information like ‘STOPSPAMNOW’ to pick up the STOPSPAMNOW newsletter, you can whitelist based on the senders email address or you can use a combination of both, which is preferable.
Hopefully these few short tips will help you in setting up effective anti spam filters.
