Smarter *From* in IMP's Compose window

[Jan Carlson]

Using imp-2.2.3-1.noarch.rpm and horde-1.2.3-1.noarch.rpm.

Suppose the imap server handles email addresses for red.com and
green.com
How can IMP display the right value in the From field of the Compose
window?

There is only ONE VALUE to set: $default->from_server in
horde/imp/config/defaults.php3.

How do I make IMP intelligently fill in the From field,
so that return addresses will be correct?   Can IMP
be configured to use LDAP or something else to look up
the right domain name?
