I spent hours today trying to fix Postfix, the mail-sending\/receiving utility built-in to every OS X install (at least with the developer tools). My ISP had blocked me a few days ago due to large amounts of spam that were getting relayed through my server, resulting in hundreds of undelivered emails being sent to my account. Today I discovered that my initial attempts to filter out this spam were not successful. Using this article<\/a> as a guide, I tried again today.<\/p>\n

I figured out I was editing the wrong main.cf file, for one thing. Apparently mailq uses one, and there’s another in \/sw\/etc\/postfix that is used as well. I configured it pretty tightly so it should be fine now – I hope.<\/p>\n

Yesterday I looked into having an external company host my sites. There’s a few disadvantages to hosting yourself, such as speed, reliability, and expensive equipment\/software. I currently host five sites on my 1Ghz G4 iMac. It’s done a great job so far but I don’t even have the awesome server software Apple makes. I have configured apache, postfix, etc by hand!<\/p>\n

I quickly discovered that a new server for my sites wouldn’t be any easier. For one thing, I’d have to pay them. They also restrict some things and charge extra for others. Also, when I develop new sites I can save and instantly see them on the web, without uploading via FTP. I decided to stick with my current setup, capped upload speed and all. For you geeky end users, how does my site loading time compare with other normal sites out there? I realize my server can’t compete, but how bad is it really? Perhaps even some ping times would be nice, especially from different states!<\/p>\n

Well my mail is back to working status, and I did it myself. Hosting my own sites, if nothing else, has provided me with a sense of accomplishment over the years. I run websites, something that is normally done by big companies with dedicated equipment. It makes me feel geeky.<\/p>\n","protected":false},"excerpt":{"rendered":"
