I know I haven’t posted for a long time on this site, but I have been busy with other email related activities and I wasn’t sure if this site was point people to where I am currently working on these projects.

I’ve been working on creating an open source email server in Erlang and I’ve been posting my activity over at http://erlsoft.org

Most of the project has been taking a lot of what I learned form SFE and making it available to anyone who wants to use the code. The project is also up on Google Code at http://erlmail.googlecode.com

The SMTP server it pretty stable at this point and I’m spending most of my time on the IMAP modules, mostly on the server. I’ll put together a POP server once I have the IMAP stuff working.

I recently created an anti-spam module that is mostly some hooks into the SMTP server that will allow for functions to be run on each email message before and after is have been save to the message store. The hooks I have in place would allow me to re-create SFE within ErlMail without having to recompile the ErlMail application, the only thing I would need to do is list the appropriate modules and functions in a config file and the next time the server restarts those checks would be active.

This approach would allow me to create a complete open source email server and still have the SFE components private is I choose to.

I am also designing a modular message store into the ErlMail server to allow for separate message store for different purposes. This would allow me to keep one message store fore the SFE servers and a separate message store for the email server that is access by the users on the same cluster of Erlang servers. This is a design specification that came directly from my work on the SFE project.

In the end, the ErlMail project would allow me to create the SFE project using the ErlMail server and most likely less then 1,000 lines of additional code, since all the real work is being done by ErlMail
