All this is possible with builtin features for years.

Hi guys,



I noticed that under IMP4 there is no function like 
imp_expand_fromaddress($imp). So if I want to compose a new mail on a 
fresh installation, as "From" address there you can see 
"user.domain.tld@hostname" instead of "user@domain.tld".



I made some changes to get it work again, but perhaps there is an 
other way to enable this function which I didn't find.



My changes (backup) to the origin source (current):

          $this->_fromList[$ident] = $val;

I also added these lines to my imp/config/conf.php:



[..]

/* CONFIG END. DO NOT CHANGE ANYTHING IN OR BEFORE THIS LINE. */

if (!function_exists('imp_expand_fromaddress')) {

     function imp_expand_fromaddress ($imp) {

         $db = mysql_pconnect($db_mail_host,$db_mail_user,$db_mail_pass);

         mysql_select_db($db_mail_database,$db);

         $user= $imp['user'];

         $sql = "SELECT alias FROM virtual WHERE username = '".$user."'";

         $result = mysql_query($sql,$db);

         $name = mysql_result($result,0,"alias");

         return (empty($name) ? $imp['user'] : $name );

     }

}



The alias-field comes from another database, not horde.

So it works again. Perhaps I missed something to get multidomains to 
run without these patches.
