How to send/receive mail in Laravel application

Im trying to include an email feature in my application where a user can send and receive their emails from their domain. I figure I may be able to use imap for the receiving but how to set up for sending from that users email address?

So in other words, imagine I have [email protected], my application will have a menu item called "Email" and when clicked it displays the users emails from within our application, eliminating the need for them to constantly check their email using their mail client (just more convenience then anything). The user also has the option to reply or compose emails to be sent from their email account.

Anything I am finding online is specific to how the application can send emails which I already know how to do. Can anyone provide any direction on best practices or packages to allow me to do this? Just looking for general direction to get me started.
