This is an IMAP server written in Go. It is a work in progress.
In the demo subdirectory is an example IMAP server that starts up on port 1193. To run this server:
$ go run ./demo/main.go
You can connect to this server using telnet or netcat. For example:
$ nc -C localhost 1193
* OK IMAP4rev1 Service Ready
* LOGIN test anypassword
* OK LOGIN completed
* CAPABILITY
* CAPABILITY IMAP4rev1
* OK CAPABILITY completed
* SELECT inbox
* 8 EXISTS
* 4 RECENT
* OK [UNSEEN 4] Message 4 is first unseen
* OK [UIDVALIDITY 1] UIDs valid
* OK [UIDNEXT 9] Predicted next UID
* OK SELECT completed
* LOGOUT
* BYE IMAP4rev1 Server logging out
* OK LOGOUT completed
The server is not fully operational on its own. It requires a mailstore and an authentication mechanism.
It defines an interface in mailstore.go which describes the service it needs from a Mailstore. For example a Mailstore could serve its data from: database, filesystem, maildir, etc... At the moment only one mailstore can be used at the same time.
To add a new IMAP command the usual steps are:
- Add the command to parser.go
- Add the command and its client interaction to commands.go
- Put the main functionality in session.go.
