Mail Autoconfig Revived

This fork revives mail_autoconfig for my Email-API Sunnybox.io. It has been updated to support the latest Mozilla ISPDB location and format. I plan on adding new features like DNS SRV Records and general DNS lookups. Right now it works as a drop-in replacement.

A ruby gem to detect and parse any Thunderbird autoconfig file for a domain. Includes a copy of the Mozilla ISPDB (Nov 2023).

For general information about autoconf visit (https://developer.mozilla.org/en-US/docs/Mozilla/Thunderbird/Autoconfiguration), for the autoconfig schema you should have a look at (https://wiki.mozilla.org/Thunderbird:Autoconfiguration:ConfigFileFormat).

Although I've tried to keep parsing as accurate as possible, there may be omissions or errors. Please feel free to submit a patch in these cases.

Installation

Add this line to your application's Gemfile:

gem 'mail_autoconfig_revived'

And then execute:

$ bundle

Or install it yourself as:

$ gem install mail_autoconfig_revived

Usage

Generally, you just want to get any associated configuration for an email address. In this case we'll use '[e-mail]'.

client_config = MailAutoconfig::for_address('[e-mail]')
client_config.short_name
=> "GMail"
outbound_server = client_config.outgoing_servers.first
outbound_server.protocol
=> "smtp"
outnound_server.hostname
=> "smtp.googlemail.com"

When searching for a configuration, autoconfig first looks to it's local database for the domain of the address, if this fails it will check http://autoconfig.#{domain}/mail/config-v1.1.xml and then http://#{domain}/.well-known/autoconfig/mail/config-v1.1.xml. If both of these fail, Autoconfig will then look up the MX records for the address, and perform the same searches on the domain of the primary MX record.

Updating the database

You may wish to update the database at some point to fetch the latest from Mozilla's ISPDB, just run the rake task rake fetch_ispdb.
