Is it possible that this IMP login problem is sue to incompatible use of 
domxml? 

Dennis Ortsen wrote is an old horde faq mailing list (circa 2003) that 
lack of domxml support might cause login failure.  If I check my PHP 
environment via http://harbell.homeip.net/phpv.php it says I have domxml 
enabled.  But if I use horde's test 
http://harbell.homeip.net/horde/test.php it say I don't.

According to PHP, in PHP5 domxml has been replaced by DOM. Domxml 
extension is not compatible with PHP5, and DOM is built into PHP5 
(http://us3.php.net/domxml , http://us3.php.net/manual/en/ref.dom.php).  
Please correct me if I'm not reading this correctly.

So the questions are: 1) does anyone suppose that domxml is at the root 
of this login problem? 2) If yes, then has anyone gotten IMP to login 
with PHP5? 3) ... on Win32?
