[imp] Horde accessing Exchange 2007 via POP3 or IMAP

[Games, Dax]

Great suggestions.  I don't think I can do the first suggestion but Iwill look into it.

How can I do this recompile of c-client and php imap and be able to easily and QUICKLY fall back if something breaks.  This is a production environment of about 2000 users.

The version of c-client your PHP installation is probably linked against 
kerberos.   If your exchange server is advertising the ability to do 
kerberos authentication, c-client will try to use it.  I believe that 
c-client will want to use the best authentication method available, and 
kerberos is far better than plaintext, cram/md5, etc.

Things to try..
- prevent the IMAP/POP server from advertising the ability to accept 
kerberos authentication
- try rebuilding c-client w/o kerberos  (you'll also need to rebuild the 
php imap extension, depending on how things are linked)
