I work with email and Postfix. On every mailing machine I have Postfix setup on, I have at least 2 instances, sometimes more (in fact, sometimes its as many as 6 instances). I was recently setting up a new set of mailers and decided to give Postfix multi-instance seutp a try. It was excellent. There …
There are a lot of people who say, “if it isn’t monitored, then it isn’t a service.” The problem is that I don’t think enough people outside of the systems world believe that or even understand why its said. I think the primary offenders here are developers. It isn’t because they don’t know better, but …
I use Capistrano to deploy my webapps and have been for a while. I also deploy right from my laptop quite frequently. So I was a little taken aback when I could deploy in one place and not in another. It turned out that Capistrano was having issues with deploying to multiple servers. In fact, …
My company signed a contract for a provider that uses TZO as their DNS provider. Now I have used TZO before (circa 2006-2007) and although their interface was archaic and there was no API, I accepted it because I was told they were reliable.

I recently had to setup daemontools on a CentOS system. I had set it up before but it had been a while. So I Google’d around and found very little and what little I did find wasn’t very helpful. So here is a quick and dirty on setting up daemontools. I even included the CentOS …
I use Bash one liners a lot. I think they are an important part of any programmers and sysadmins toolkit. If you can’t write a bash one liner, even a simple iterator, then you really need to learn. I promise it will make your life infinitely more pleasant. Frequently I find myself writing things that …
On the same day that Goodmail removed Yahoo! from its pool, it added the vastness of Microsoft domains. These domains include hotmail.com, live.* and msn.com. The addition of Microsoft to the Goodmail community is a good thing because it means that Microsoft is starting to play ball in the email community. However it comes as …
So as of today, Yahoo! will no longer be accepting Goodmail imprinted messages. There is currently no press release from Goodmail, but I am sure one will be forthcoming. The latest reference to the on goings is listed here in one of their recent blog posts. Goodmail claims that they are doing everything possible to …
The more I branch out my interests (or skill sets), the more I find myself joining communities. I am a part of Yelp (food/restaurants), StackOverflow (programming questions), Codaset (social coding), Facebook, LinkedIn (professional networking), Disqus (blog comment system), and the list goes on and on for many of my interests. There are lots of communities …
