[imp] Login Failure

[Horde]

Greetings,

We are in the process of moving to a new web host.  We were using 
Horde Groupware 1.1.1 on a shared Linux hosting account with a CPanel 
Control panel and MySQL.  Everything was working fine on the old 
host.  After moving the Horde over to the new Host we see the Horde 
log on page but we are now getting a "Login Failed". We are unable to 
login to any mailboxes on the new host nor mailboxes outside their network.

The new host is a Linux shared hosting account with Hsphere and 
QMail.  We ran the test.php and the "IMP Test" and everything checked 
out.  We attempted to run the "PHP Mail Server Support Test" and it 
just hangs until it times out.  According to the Hsphere Control 
Panel the Logon Failure is not creating any errors in Apache Error 
Log nor is the Horde creating any errors in imp/error_log.  I 
contacted the new Host and they informed me the IMAP is "IMAP 4" and 
the port is standard 143.

Any help would be greatly appreciated.

Thanks in advance!
