[imp] Changing From address field in "message compose"

[Bianchi Quota Leonardo]

Hi! I sent an email just yesterday.. 

Is it possible configure IMP so that when I send an email with compose in
the field From (and also set in Replay address (ctladdr)) is shown the
address as specified in aliases?

i.e. 
red.blue:pink88 at dominio.com

"From" should be: red.blue at dominio.com instead of pink88 at dominio.com as it
is now (default identity)

Thank You very much!!

Leo.
