[imp] Horde accessing Exchange 2007 via POP3 or IMAP

[Games, Dax]

I am trying to setup Horde/IMP to login via POP3 or IMAP to an Exchange
2007 server.  Please don't ask WHY!

Let's just say it is a requirement of the client.

All host names and user ids below have been changed for security
reasons.  

POP 3 and IMAP both work via a third party email client with no special
settings. My server config from servers.php is below:

$servers['mail'] = array(
    'name' => 'Mail',
    'server' => 'mail.host.com',
    'protocol' => 'pop3',
    'port' => 110,
    'folders' => '',
    'namespace' => '',
    'maildomain' => 'host.com',
    'realm' => 'host.com',
    'preferred' => ''
);

When I test authentication via http://horde.host.com/horde/imp/test.php
I get:

server="mail.host.com" user="user1"
mailbox="{mail.host.com:110/pop3}INBOX"

array(1) { [0]=> string(99) "Certificate failure for host.com: unable to
get local issuer certificate: /CN=mail" }

Any ideas?

Thanks,

Dax
