[imp] IMP login failur

[Leonardo Podda]

Hi,
I've installed Horde 3.0.6 and IMP 4.0.4.
Horde go very well. I use mysql authentication and I haven't problems. I
have a problem with login in IMP, I can't do login and when I launch the PHP
IMAP SUPPORT TEST from ../horde/imp.test, I obtain this answer:
*Attempting to automatically determine the correct connection parameters for

What's the possible problem?
Thanks in advance
