OpenDKIM and Postfix configuration question
by Jason White 17 Dec '16

17 Dec '16

Postfix is configured on my server to use SASL authentication for messages submitted via port 587. OpenDKIM has been set up for both signing and verification. In /etc/opendkim.conf, InternalHosts refers to a file that lists various addresses, including the IPv6 range of my home network, as well as my domain name (".jasonjgw.net"). Consequently, messages submitted by hosts on my home network are signed by OpenDKIM. However, if, for example, I take a laptop to a different network and then attempt to send mail from it via port 587 on the server, it isn't signed, even though it has been authenticated with SASL in the Postfix session. Obviously, it doesn't match any of the addresses given in the InternalHosts file. Is there a way to configure OpenDKIM to sign messages from hosts that have SASL credentials, regardless of which network they're on?

New Device Suggestions
by Piers Rowan 10 Dec '16

My kids school are getting Toshiba Portege Z20t so I checked them out and they look interesting. Basically it is a laptop / tablet machine. The important criteria for me include: - Runs Linux WELL - laptop / tablet / touch screen - Long battery life - Fast / Responsive - As large a screen as possible I have never used a touch screen version of Linux. Can anyone recommend similar devices? Are their any pitfalls with touch screens (GNome vs Unity)? Thanks

Your search history at Google isn't available to your local government unless Google cooperates with them. If a Google search redirects you to a major news site like the New York Times it wouldn't reveal much if they used HTTPS, but they however choose not to do that and additionally have 77 cookies from different advertising sites, Facebook, Google, and others when you view one of their pages. https://panopticlick.eff.org/ If you view web sites with Tor then their ability to track you is greatly reduced. Tor with your regular browser can still be identified, visit the above site to discover how easily it can be done. Tor with torbrowser (package torbrowser-launcher in Debian, it works in Jessie but is broken in Unstable) is very hard to track. Tor with your regular browser is adequate to stop the basic snooping as described in the article you cited. https://www.privateinternetaccess.com/ If you want to protect against very basic snooping while still getting good transfer speeds (Tor slows throughput and increases latency) then a VPN such as the above is a good option. They block SMTP (for obvious reasons) and would not be suitable for serious crimes such as wholesale drug dealing. But for using Bittorrent to download movies and to escape casual surveillance by your own government they are good. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

At the moment, I have no strong opinion one way or the other (but with a slight leaning towards "why? what's the point?"), but would like to know if there's any reason why I should have such an opinion. if the LUV lists and meetings continue as before and there's no risk of losing autonomy, just easing of the administrative overhead then I can't see any reason to object. craig -- craig sanders <cas(a)taz.net.au>
