Recently I registered the domain name http://www.erlmail.com with the intention of using it to create a free open source email server for Erlang.
Currently it is pointing to SpamFreeEmail.com, mostly because this will be the original code base for the project.
My intention is to create a complete SMTP compliant server with IMAP4 and POP3 support. I want it to be easily distributed and highly concurrent, hence the choice of Erlang.
I have never even participated in an open source project before, so running on will be quite a learning curve for me 
I have the core of the SMTP server and much of the queuing processes already designed for SFE. A decent amount of code will need to be removed from SFE as it pertains exclusively to how I have my system configured, although some of it may simply get put into configuration files.
I’m hoping that I can get the core of a server up and running within a month or so. I still need to continue developing SFE, but I think developing them concurrently will improve them both.
So if you are interested in help, let me know. If you are interested in using the final project, let me know. Either way the more interest in the project the better and faster it will get done.
