How To Block Spam Before It Enters The Server (Postfix)

Filed under

HowTos

The last few weeks have seen a dramatic increase in spam (once again). Estimates say that spam makes now up for 80 - 90% of all emails, and many mail servers have difficulties in managing the additional load caused by the latest spam, and spam filters such as SpamAssassin do not recognize large parts of that spam as they did before. Fortunately, we can block a big amount of that spam at the MTA level, for example by using blacklists, running tests on the sender and recipient domains, etc. An additional benefit of doing this is that it lowers the load on the mail servers because the (resource-hungry) spamfilters have to look at less emails.

Howtoforge articles

Wow, go figure, a site named Howtoforge has a new article that, wait for it, tells you howto do something.

Do we really need to have all the news sites (including Tuxmachines) announce each and every article that shows up on Falko's site?

This isn't news, it's blog spam.

I for one am interested

Thank you for posting it!
