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

Filed under

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.

Community chest: Storage firms need to pay open-source debts

Linux and *BSD have completely changed the storage market. They are the core of so many storage products, allowing startups and established vendors alike to bring new products to the market more rapidly than previously possible. Almost every vendor I talk to these days has built their system on top of these and then there are the number of vendors who are using Samba implementations for their NAS functionality.

Did Red Hat’s CTO Walk – Or Was He Pushed?

He went on to say that some within Red Hat speculate that tensions between Stevens and Paul Cormier, Red Hat’s president of products and technologies, might be responsible, although there doesn’t appear to have been any current argument between the two. Cormier will take over Stevens’ duties until a replacement is found. Vaughan-Nichols also said that others at Red Hat had opined that Stevens might’ve left because he’d risen as high as he could within the company and with no new advancement opportunities open to him, he’d decided to move on. If this was the case, why did he leave so abruptly? Stevens had been at Red Hat for nearly ten years. If he was leaving merely because “I’ve done all I can here and it’s time to seek my fortune elsewhere,” we’d expect him to work out some kind of notice and stay on the job long enough for Red Hat to find a suitable replacement. Turning in a resignation that’s effective immediately is not the ideal way to walk out the door for the last time. It smells of burning bridges. Read more
