hi list, has anybody made any progress, or given out any code for  
this? Basically, i am looking for something like qpsmtpd  
([http://smtpd.develooper.com/](http://smtpd.develooper.com/)), only written in Ruby, so that i can  
modify it as i please, and learn Ruby at the same time.

I’ve searched the net, and the ML archives, but havent found anything  
specifically useful, except maybe  
[http://blade.nagaokaut.ac.jp/cgi-bin/vframe.rb/ruby/ruby-talk/222992?222943-226481](http://blade.nagaokaut.ac.jp/cgi-bin/vframe.rb/ruby/ruby-talk/222992?222943-226481)  
(but which still doesnt give out any code). Has anybody worked on, or  
is working on, something like this?

Well, I don’t know if it will be of any use for you, but… Basically,  
I was aiming at replacing amavisd on my mailservers, so I wrote a small  
smtp daemon that could be inserted between two postfix daemons to call  
some external filtering processes.

Trouble is the code is quite immature (the project has never seen the  
light), and uncommented, so I’m not sure it will be a very valuable  
learning experience…
