AeroMail is a web-based e-mail client written entirely in PHP using PHP’s built in IMAP functions. I wrote AeroMail because I didn’t like the way any other web-based e-mail packages looked or worked, and also because I wanted to get used to writing with PHP. AeroMail is not entirely complete or foolproof, but I think that I’ve got a good start on it.
AeroMail must run on the Apache web server installed with the PHP module. The PHP module also has to have the IMAP functions compiled into it. AeroMail uses Basic HTTP authentication to pass the username and password to the IMAP server, and does not store a cookie or leave traces in your cache. Because of this, I would recommend running AeroMail with a SSL server if it is to be used on a high traffic site.
