MobileMail
MobileMail is a minimalist mobile phone mail gateway for those with their own webserver, a phone capable of basic (X)HTML and exorbitantly expensive UK GPRS/3G charges.
It allows POP or IMAP access to remote/local mailboxes and presents a simple interface that allows you read/send and reply to emails.
Requires Python, CGI, IMAP (or POP) access to your mailbox(es) and an accessible SMTP server for sending.
