<p>What&#8217;s the best way of extending Mail.app with <a href="http://www.gnupg.org/">GPG</a> functionalities?</p> <p>Google gave me too many answers..</p> 77 gpg-for-mail-app 2007-12-17T04:39:02-08:00 <p>After several years using the <a href="http://en.wikipedia.org/wiki/Mbox">mbox</a> format on my personal email server, I decided that it was more than time to move to a better format: <a href="http://en.wikipedia.org/wiki/Maildir">Maildir</a>.</p> <p>The move was triggered when I started to have real problems consulting the boxes remotely over <span class="caps">IMAP</span> (I use <a href="http://www.dovecot.org/">dovecot</a>). The folders started to get messed up and the system was slow.</p> <p>I always knew that maildir have clear advantages for my scenario, but I thought that I would have a hard time migrating my services and scripts. I was surprised how easy it was when I really got my hands dirty!</p> <p>First, used a great Perl script <a href="http://packages.debian.org/etch/mb2md">mb2md</a> to convert my existing mailboxes. Then changed some lines on my <a href="http://www.postfix.org/">Postfix</a> configuration. Since I do my mail processing with the Perl module <a href="http://search.cpan.org/perldoc?Email::Filter">Email::Filter</a>, it was just a mater of changing the paths, and it worked magically!</p> <p>Never thought it was so easy&#8230;. Oh, and dovecot now behaves correctly :-)</p> <p>Goodbye mbox, you served me well&#8230;</p> 71 from-mbox-to-maildir 2007-11-27T06:40:49-08:00 <p>Two days ago, I was playing with DNSStuff (<a href="http://dnsstuff.com">http://dnsstuff.com</a>), doing some checks on my domain &#8220;0x82&#8221;. One of the tests was about some <span class="caps">SPF</span> thing that I never heard about.</p> <p>It told me someone could send an email from anywhere, and make it appear that it was send from my domain, making it legitimate (ok, I know that this doesn&#8217;t make my email secure by himself). It told me that the solution was a <a href="http://www.openspf.org/">SPF thing</a>.</p> <p>I&#8217;ve started reading about it, and realized that, although it seems a big hack (what? using the <span class="caps">TXT</span> field of a domain to store data??), it could help and protect your email. For that I needed to change the <span class="caps">TXT</span> record of my domain (try <code>dig TXT 0x82.com</code> on your console).</p> <p>Then, to make sure that the email I receive is tested against this specification, I had to configure my <a href="http://postfix.org">postfix</a> SMTP server. If you search on google for &#8220;postfix spf debian&#8221; you will find nice tutorials on how to implement that. It was really simple!</p> 52 protecting-your-domains-email-with-spf 2007-09-15T17:09:46-07:00
