SPF the easy way

Tags: 

Sender Policy Framework (SPF) is an open standard that aims to help prevent spam, and stop legitimate email from being tagged as such. While the specifications can take some time to understand, there are some web-based tools to help you make creating your SPF records a little easier than by hand, but I still find them to be a bit misleading. According to the SPF FAQ the simplest way to create your SPF record is to simply list the IP addresses of all servers that mail goes out through, e.g.:

v=spf1 ip4:192.168.0.10 ip4:192.168.0.12 ~all

and just add more "ip4" strings for each address. Then just paste it into a TXT record in your domain's DNS and you're good to go!

Tip: Moving RedMine to another server, don't forget the files

Tags: 

This past week I moved an install of RedMine from one server to another, or rather I just moved the database over and checked out the SVN code again. After getting it going correctly I promptly forgot about the fact it was at a new location and just worked away on my assigned tasks. Well, as it turns out I'd completely forgotten about the uploaded files, which now wouldn't download anymore. The problem was that I forgot to verify where the attached files were stored, and it turned out to be in "files" directory, so now I have to manually copy those few files over and all will be well.
