Google mail and moz-box-shadow inside html message

Anyone knows where i can read about all css params that gmail disallow(filter) inside message?

For example, i have noticed, that moz-box-shadow is not allowed.

Btw about html tags, i guess iframe isn't allowed as well. List of tags would be nice. :)
