I am tired tonight after spend fury amount of time of anti-spam and other alike for my comany’s mail server. We are using SME 7.xx… it a linux based solution and a varient of CentOS. It works fairly decent and not a whole of issues to complain about. I am assuming that most “home grown” web / mail servers deal with alot of “spam issues”. I relize that thier is no 100% spam proof filtering system but there is some preventive pratices that you can do to reduce the amount of spam.
Here are SOME tips that can help reduce the amount of spam:
1. If you give out your email address out (to unknown sources) your likely to get spammed.
2. Forwarding Mail: Don’t recieve or send Forwards they might contain bots that harvest email accounts (like yours).
3. When posting your Email address online. Use human logic not computer logic. yourname@domain.com can be harvested by the way it delimited. use something similar like this: yourname {atsign} domain [dot} com.
4. Signing up / Forums: If you sign up for forums or freebies. Use a “spam account”. use gmail or other free account services.
5. Setting your email address: use something that is easy to remember but not easy to make up. Spammers use a techiques of probility. using common names such as hottiegrlchick@some-domain.com
6. Changing your password often or use a strong password. that is aleast 8 charaters long and using numbers, letters and non-letter/numbers.
Hope some of these tips help you along your journey in inter-space
