[horde] Can't send mails after using Cyrus Imap

[Krishna]

Hi,
      After configuring Cyrus IMAP, I can't send mails via IMP. I am using 
the Head version of both
Horde and IMP.
I don't even see any log coming up. But I can send mails through 
Outlook/Eudora.
Plus I still don't know why I don't get a confirmation screen even after 
activating in the /imp/conf/prefs.php file.

On servers.php I have specified the correct smtp host.
Has anyone got Cyrus working with Horde/IMP?

regards
Krishna
