After playing for some time with DNS Stuff, I decided to configure SPF for mamchenkov.net domain. I don’t have a lot of expectations, but I hope that it’ll help to fight all that SPAM that we have on the web. As a side effect, hopefully emails to Hotmail and Yahoo! will start working again. I don’t have a lot of those myself, but a few people who email from my server complain once in a while.
If you are interested, my SPF string looks like this: IN TXT "v=spf1 a ~all". It was extremely easy to create using this wizard.
This is the first in a row of changes for my mail server setup. Planned works will cover better anti-SPAM and separation of users and mailboxes into domains (right now everyone can use any hosted domain).
Let me know if you have any suggestions for improvements, or if you have noticed any problems.
