I am developing a basic yet highly customized CRM for a small training centre which has the ability to store student records and also send emails to them. I\'m using SwiftMailer
You will want to pipe your email to PHP and use stdin:// to read the contents of the email and add the e-mail to your database.
I've done this with cake and the simplest way is to make a Cake console application to handle the parsing. Also using cpanel's account level filtering to generate the pipe is really simple.

Sounds like you want to include SwiftMailer as a Cake plugin, amirite?

-- if you want to package it yourself. Otherwise, a cursory search of the Bakery yielded this result:

Hopefully it will at least get you pointed in the right direction. HTH. :)
Thanks to everyone for your answers, but I've been doing some more searching and it looks like the solution is actually incredibly simple.
Basically, with the help of a plugin, I can set up the mail server in databases.php as a datasource and then write a Model and Controller to interact with it.
Here's the example I found: https://github.com/kvz/cakephp-emails-plugin
Edit: the repo has been deprecated and is now available at https://github.com/kvz/deprecated/tree/cakephp-emails-plugin
