maildir

maildir

A go package for reading and writing messages in the maildir format.

The Maildir e-mail format is a common way of storing e-mail messages, where each message is kept in a separate file with a unique name, and each folder is a directory. The local filesystem handles file locking as messages are added, moved and deleted. A major design goal of Maildir is to eliminate program code having to handle locking, which is often difficult.

Installation

You can download the package using

go get github.com/amalfra/maildir

Usage

Next, import the package

import (
  "github.com/amalfra/maildir"
)

Create a maildir in /home/amal/mail

myMaildir := maildir.NewMaildir("/home/amal/mail")

This command automatically creates the standard Maildir directories - cur, new, and tmp - if they do not exist.

Add a new message

This creates a new file with the contents "foo"; returns the Message struct reference. Messages are written to the tmp dir then moved to new.

message, err := myMaildir.Add("foo")

List new messages

mailList, err := myMaildir.List("new")

This will return a map of messages by key, sorted by key

List current messages

mailList, err := myMaildir.List("cur")

This will return a map of messages by key, sorted by key

Find the message using key

message := maildir.Get(key)

Delete the message from disk by key

err := maildir.Delete(key)

Below are the methods that are available on Message instance

Get the key used to uniquely identify the message

key := message.Key()

Load the message content from file

data, err := message.GetData()

Process message - move the message from "new" to "cur"

This is usaully done to indicate that some process has retrieved the message.

key, err := message.Process("new")
