Mailgun 5.0.0

⚠️Breaking changes⚠️
This release of mailgun allows a user to mock MailgunProvider for testing and also uses the correct EventLoop for Request

extension Application.Mailgun.Provider {
    static var fake: Self {
        .init {
            $0.mailgun.use { app, _ in
                MockMailgun(eventLoop: app.eventLoopGroup.next())
            }
        }
    }
}

This release also renames the package name and url to be more concise.
So now installing mailgun will look like

.package(url: "https://github.com/vapor-community/mailgun.git", from: "5.0.0")

.target(name: "App", dependencies: [
    .product(name: "Vapor", package: "vapor"),
    .product(name: "Mailgun", package: "mailgun")
])

Vapor 4 support

Mailgun now supports Vapor 4! Development for Vapor 4 will be done on master from here on out and Vapor 3 development will be done on the vapor3 branch.

import Mailgun

// Called before your application initializes.
func configure(_ app: Application) throws {
    /// case 1
    /// put into your environment variables the following keys:
    /// MAILGUN_API_KEY=...
    app.mailgun.configuration = .environment

    /// case 2
    /// manually
    app.mailgun.configuration = .init(apiKey: "<api key>")
} 

// call it without arguments to use default domain
app.mailgun().send(...)
req.mailgun().send(...)

// or call it with domain
app.mailgun(.myApp1).send(...)
req.mailgun(.myApp1).send(...)

Support Multiple Domains

You can now use multiple domains to send emails with Mailgun

let mailgun = Mailgun(apiKey: "<api key>")
services.register(mailgun, as: Mailgun.self)

// Put this extension at the bottom or create a new file for it
extension Mailgun.DomainConfig {
    static var euDomain: Mailgun.DomainConfig {
        return Mailgun.DomainConfig("mg.example.com", region: .eu)
    }
    static var usDomain: Mailgun.DomainConfig {
        return Mailgun.DomainConfig("mg2.example.com", region: .us)
    }
}

mailgun.send(message, domain: .euDomain, on: req) 

The new major version for this release is 3.0.0 to align with the supported Vapor version. 4.0.0 tag coming soon.
