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/v2Usage
Next, import the package
import (
"github.com/amalfra/maildir/v2"
)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")Development
