Mailman is an incoming mail processing microframework (with POP3 and Maildir support), that works with Rails “out of the box”. - Jonathan Rudenberg, author of Mailman.
I came across mailman a couple of weeks ago on Railscasts, and immediately began looking for a chance to implement it in my work at NetEngine.com.au. Things set off quickly, starting with Ryan Bates’ code and ideas and going from there, but I don’t have very much experience just yet in the ruby/rails world and I quickly ran into some problems that I couldn’t just fix with a quick trip to google and stack overflow. Realising of course, that everything I’ve learned about Rails is these last couple of months since I began has come from someone who’s taken the time to put together a tutorial, I thought I should boot-up DanSowter.com and start writing something that might help the 10 people with less experience than me.
