wrong from field with alpine

[Pierre Frenkiel <p.frenkiel@laposte.net>]

hi,

when I send a mail with alpine, the from field becomes 
"frenkiel@laposte.net" instead of "p.frenkiel@laposte.net"

An obvious consequence is that people can't reply to this mail

that looks like an alpine bug. I'll then make a bug report, unless 
somebody tells me what I'm doing wrong.
