We have a membership-based site developed using PHP and MYSQL and we also have another site using WordPress.
We need to be able to have our members send emails to outside email addresses like Gmail, Yahoo, etc and when that person with a Gmail account sends an email back, it will go to the members email inside our website. Each member needs to have an inbox, deleted, and sent folder.
As a member signs up they need to automatically be able to have an internal email set up.
If you know of a plug-in and can make it work or if you have done this before from scratch, I am interested in hiring you.
If you are that person I can supply more details.
