`go-mail` free of third party dependencies and only depend on the Go Standard Library, we \nintroduce a Middleware concept in version v0.2.8. This allows the user to alter a `mail.Msg` according to their \nneeds by simple implementing tool that satisfies the `mail.Middleware` interface and provide it to the `mail.Msg`\nwith the `mail.WithMiddleware()` option. This allows the use of 3rd party libraries with `go-mail` mail messages, \nwhile keeping `go-mail` itself dependancy free.\n\n### List of currently supported middlewares\n\n* [dkim](dkim): DKIM (DomainKeys Identified Mail) middleware to sign mail messages\n* [openpgp](openpgp): OpenPGP middleware to digitally encrypt and sign mail messages (Experimental/Development on hold)\n* [subject_capitalize](subject_capitalize): Capitalizes the subject of the message matching the given language\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fwneessen%2Fgo-mail-middleware","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fwneessen%2Fgo-mail-middleware","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fwneessen%2Fgo-mail-middleware/lists"}
