We have a web app that we are selling to clients. We have it running on a web host. This web host has TOS for doing mailings, and has requirements like unsubscribing after five bouncebacks. We are going to comply fully with CAN SPAM and the web host's TOS.
Part of the app's functionality is that our client's customers can sign up for a couple different mailing lists.
I looked at PHPList, and it seems to be an all-in-one solution; I need a library or framework something so that I can manage our own lists that are integrated into our web app.
I guess the bottom line is that I need a PHP library that can act as a mail client and log onto an account for checking bouncebacks. I don't want to create a webmail site; I just need (at the minimum) a library to have a script log on and check for boucebacks, so I can delete them from the mailing list. I need to make scripts that can check email accounts.
Is there something already out there that I can use?
