AWS SES + Postfix + DKIM
May 28, 2013
For the last year or so I’ve been using SendGrid to relay all emails coming from my server. I don’t send a lot of emails through the system; it’s mostly notifications from the blog and a few related automated messages. While I like paid version of SendGrid (which I’ve used at work), the free version is lacking a few features and includes an unsubscribe link on emails which is really annoying. I decided to mix things up a bit and give Amazon Simple Email Service (AWS SES) a shot. Along with SES I wanted to configure all my mail to be signed with DKIM, on my server. I hope the internet continues to allow the anonymity it currently does, but that comes with a price (because people are abusive bastards), and that price is trust. DKIM is like trust, for email!
Getting underway with IPv6
July 6, 2010
So let me start off by saying, I’m not new to the world of networking. I’ve been doing this for a long while now. I had a Linux box running as a router on a PPPoE DSL line back before you could even buy a home “router” (IE Linksys). Heck, I had the network running before Pac Bell even had tech support that could handle the concept of more than one computer on a DSL line (and let me tell you, mentioning the word “Linux” around them was hilarious). You’d think that since I’ve been doing this for so long, I must have experience with IPv6… but I don’t. There are a few reasons for this: A) No ISP or server host I’ve ever used has provided IPv6 addresses B) IPv6 has really only started to “pick up” in the last 2-3 years and most importantly C) I’ve never had a need. If you don’t have the need or the access, why bother putting the effort into trying to fight it? Besides, while IPv6 introduces a lot more features into the core stack than just more addresses, I expected it to work mostly the same on a basic level. As it turns out that only seems to be the case in the server world, at home that is not exactly the case.
