#94 email field in user and from_address field sizes are off

[Jay Bonci]

The user.email and the mail.from_address fields are
inconsistant in their sizes. user.email allows 40
characters, while mail.from_address allows 80
characters.

They should be the same size.

These aren't connected in any way, so I'm not sure it's a
bug. It's easy to drop mail.from_address to 40 characters,
though.
