dovecot - Jun 2005 - Hang-up problems with outlook 2003 and test 1.0

Hi all, I'm testing dovecot 1.0 on a tru64 v5.1 and on a rhel3 platforms.
I've a problem when I use outlook 2003 to download mails: outlook stop
responding and hang-up when I use imap protocol.

Someone have the same problem? What should I do?

This is my configuration:

protocols = pop3 imap
disable_plaintext_auth = no
mail_save_crlf = yes
mail_read_mmaped = yes
maildir_copy_with_hardlinks = yes
protocol pop3 {
  pop3_uidl_format = %08Xv%08Xu
}
auth default {
  mechanisms = plain
  passdb = passwd
  userdb = passwd
  user = root
}
