Leverage CommandBox to install into your ColdBox app:
box install cbmailservices
This will install the module in your application so you can configure it and use it. By default, it will register a mixin helper called newMail() and a WireBox ID: MailService@cbmailservices which you can inject into your models to send mail.
It will register a default mailer that uses the cfmail protocol. You can find all of the API Docs here:
