Defined in:
lib/mailit/mailer.rb

Overview

Allows you to comfortably use the EventMachine::Protocols::SmtpClient. In order to use it, you have to first include this module into Mailit::Mailer

Class Method Details

.included(base) ⇒ Object

This assumes that EventMachine was required and we are inside the EventMachine::run block.

Since EM implements some parts of the mail building we’ll have to deconstruct our mail a bit. On the upside, it seems like it supports STARTTLS (without certificate options though)
