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

Filed under
Linux
Security
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!

Early Ubuntu 14.04 vs. Ubuntu 16.04 Intel Xeon E5 Benchmarks

This morning I posted some Ubuntu 14.04 vs. 16.04 LTS Radeon graphics benchmarks while if open-source AMD graphics driver evolution doesn't get you excited, in this article are results from other non-graphics benchmarks in comparing the Ubuntu 14.04 vs. 16.04 performance for these long-term support releases in their current form. For getting an idea how the overall Ubuntu Linux performance has evolved over the past two years for those solely riding Long-Term Support releases, I compared the performance of Ubuntu 14.04.0 to Ubuntu 16.04 LTS in its current daily ISO form. The tests were done on the same Intel Xeon E5-2687W v3 (Haswell) system with MSI X99S SLI PLUS motherboard, 16GB of RAM, and AMD FirePro V7900 graphics.

These 3 things are trying to kill Linux containers

For nearly two years, Linux containers have dominated the world of enterprise IT, and for good reason — among others, they take on issues that virtualization simply cannot within application development and computing at scale and allow for the enterprise world to truly embrace concepts like devops and microservices (the Service Oriented Architecture dream from years gone by). That sound you hear is IT vendors stampeding towards the container bandwagon, but, as with every emerging tech trend, this isn’t always a good thing, as not everyone is walking the walk, regardless of what the business might actually say.
