I'm currently working on making a library for NodeJS to provide a nice client library for IMAP. There is another library at the moment, but it doesn't provide a lot of the functionality provided by IMAP, so I wanted to write a full-on client trying to conform as much as possible to RFC 3501.Currently, it can send all standard IMAP commands and return the results, but they aren't wrapped in any particular nice response format, and there isn't any real standard method for supplying arguments yet, other than a string matching the IMAP protocol, which isn't ideal. Hopefully I will get this all finished in a more workable format in the next few weeks :)
