mailcap
A mail capture and archival server for RethinkDB.
Mailcap makes it easy to store emails in a RethinkDB database.
- Mailcap is an SMTP server so it can receive mail from any MTA.
- Emails are parsed into a JSON format that is easy to search.
- File attachments are saved efficiently using ReGrid

}How to retrieve file attachments
File attachments are stored with a path (called a filename in ReGrid) of the id of the email and the attachments filename. Per the above email example, the file would be stored at d9e31972-6eee-46bd-b63f-acee4b2cd462/swirly-ubuntu-wallpaper.jpg.
The above file could be retrieved with the following code.
var fileName = 'd9e31972-6eee-46bd-b63f-acee4b2cd462/swirly-ubuntu-wallpaper.jpg'
var ReGrid = require('rethinkdb-regrid')
var bucket = ReGrid({db: 'example'})
// initBucket creates tables and indexes if they don't exist, returns a promise.
bucket.initBucket().then(function () {
// We are now ready to read and write files
var rstream = bucket.downloadFilename(fileName)
rstream.pipe(fs.createWriteStream('./swirly-ubuntu-wallpaper.jpg'))
})
