[horde] Command stream end of file, while reading line user=??? host=UNKNOWN

[Krishna]

Hi,

   I am using RedHat 7.3 with the Horde HEAD version downloaded from the CVS
repository and Imp 3.1. I tried it with IMP3.2 but still get the same error,
when authnticating users.
But it works fine if I use the authentication method as ftp.

I wanted to know which one be better ftp or imap?

The purpose of using horde head version is to get spamassassin going, since
I was told that the previous version of horde 2.1 which I was using does not
support it.

I am using RedHat 7.3 with
php-4.2.1 downloaded rpm and others.

To get rid of this error , I even upgraded imap and also used these settings
for it in
servers.php
imap
imap/notls
imap/ssl
imap/ssl/novalidate-cert

But it doesn't work out. I still get the same error in /var/log/maillog.
Where could be the problem?

Any help would be highly appreciated.

regards
Krishna
