Virtually all linux distributions include sendmail as the default MTA. Which is okay – it has been around for a long time, is stable and it works great (although the postfix afficionados might disagree!). But it has nothing built in for spam control which is good; it was not designed for that. So you’ve installed spamassassin and it works good but you still are getting unflagged spam emails through. Perhaps you need to try greylisting.

When you’re running production servers, the one thing you don’t want to do is upgrade the kernel every time a new update comes out. Why? Because that’s the only Linux update operation that requires a reboot once it’s done—and in a production environment you often can’t have downtime.

Inbox overflowing? Sometimes it helps to show only the unread email messages, so you can more quickly scan through the list and clean out your inbox. The select Unread feature in Gmail just checks the boxes next to the unread messages, but here’s how to show only unread.

Once you’ve done so, save the script and double-click on it to start it up—you’ll be able to scroll the command prompt window with the keyboard now. Personally I prefer using Shift+Page Up or Down to scroll, since that’s the more Linux way to do it.

If you have been an admin for any length of time, you have certainly discovered situations where a server spikes in CPU use or memory utilization and/or load levels. Running `top` won’t always give you the answer, either. So how do you find those sneaky processes that are chewing up your system resources to be able to kill ‘em?
