Matt, any update on where this is actually failing?

So it doesn't fail, everything works as expected. I have no idea why 
this should not work with the itip viewer.

require '/etc/httpd/htdocs/horde/imp/lib/Identity/imp.php';



$identity = new Identity_imp();



var_dump($identity->getMatchingIdentity('me@columbia.edu'));

var_dump($identity->getMatchingIdentity('notme@columbia.edu'));

var_dump($identity->getAllFromAddresses());

var_dump($identity->getFromAddress());

var_dump($_SESSION['imp']['user']);

var_dump($_SESSION['imp']['maildomain']);



int(0)

int(0)

array(1) {

   ["me@columbia.edu"]=>

   int(0)

}

string(19) "me@columbia.edu"

string(6) "me"

string(12) "columbia.edu"

IMP_MIME_Viewer_itip is using Identity_imp->getMatchingIdentity() 
which is using getAllFromAddresses() which is using getFromAddress() 
which is building the email address from $_SESSION['imp']['user'] and 
$_SESSION['imp']['maildomain'] if the from address in an identity is 
empty. That I why switched from using Identity to Identity_imp.

Can you trace where on the road this fails?

It's available as the combination of user name and maildomain setting.

Your email address must be available to IMP *anywhere*. Either in the 
identities or as a combination of user name and maildomain setting.

I received an iTip invite where the attendee is listed as 
abc123@example.edu (aka my address) but my only option is to "Add to 
my calendar".



My "from address" is still blank in my identity.
