[erlang-questions] Store for e-mail messages

I don't know what the intended use is, but...

I'd suggest using MailDir including the method outlined for creating 
files and moving them. . I'd then build a database on top of that to 
find individual messages. This has the advantages that,

* it's easy to manage individual messages using standard unix shell 
* if it crashes you can rebuild the database using the message files
* if you suffer file system corruption it's easier to at least get some 
of the messages back.
* You can use existing tools, eg a MUA, to inspect the messages during 

If you haven't already take a look at qmail but don't copy it. It has 
some nice ideas, but (to my mind) is not easy to work with. Look at 
postfix as a good example of how to do things. There are things that it 
could do better or doesn't do, and should be easier with Erlang, eg 
distributed mail process and mail boxes.

Please keep us informed. I'd like to help if you start to make progress.

Anyway, hope that helps.
