Comments: 5 Spam is an annoyance and there's a multitude of ways to counteract it. However spammers also get smarter and try to bypass filters and stuff. In addition, ICANN has lately approved a great mean gTLDs (generic Top Level Domains), like .biz, .info etc. Some of those gTLDs are, in my opinion, exclusive used by spammers. Lately, I have gotten a lot of spam from the .xyz gTLD. So the question was, how to block email coming from such domains using that gTLD.

The problem is that they have dynamic ip addresses and most mailservers will not accept incoming mail from a server on a dynamic ip address. The solution is rather simple. Set up postfix in a way that it will relay the outgoing email through the actual ISP. In this short howto I'll show you how to do that.

The rationale behind the encryption of a complete system is that you don't have worry about what you encrypt and what not, because everything (except for the /boot) partition will be encrypted. However the problem I have encountered so far is, how could I reboot my computer from afar? I would be required to be in front of the computer and enter the password. I have wondered this far how I could reboot the computer remotely.

Author: sjau • Tags: security • Comments: 25HOWTO: Automatically Unlock LUKS Encrypted Drives With A Keyfile This howto shows how to unlock multiple devices in the intial ramdisk remotely.
