gmail-lite PHP App {gmail-lite}
http://laputa.sytes.net:83/gmailer/index.html#gmail-lite

gmail-lite is an html-only interface of GMail. It should be workable
with any browser on Earth (e.g. lynx (I really tried!), IE3, Netscape4,
mozilla5...).

Features:
* Plain html only. Not a single line of javascript is used (at the
exact opposite side of spectrum of official GMail!)
* One page summary for all standard boxes and labels.
* One click for unread conversation.
* Read, check and compose gmails in conversations and labels, which
are all still there.
* Paged threads, collapsed conversation. All still available.
* Reply to a conversation by a simple click.
* Add addresses to to, cc and bcc fields by simplying select them
from a list. Use click/Ctrl-click/Shift-click to select a list of 100
addresses instead of typing them! (This is probably the second
most-wanted feature of GMail - right after #1: "draft saving" :-D .)
* Read the original message in case your browser displayed all
kinds of Unicode garbage.
* Full search ability as in GMail, and search results come with
"preview" (or called snippet according to them).
