I am using IMP to do the authorization over imap and I am getting following error in /var/log/maillog: Sep 21 17:04:54 brain imapd[5120]: Login failed user=_brain_asp_ogi_edu auth=_brain_asp_ogi_edu host=brain.asp.ogi.edu [129.95.94.15] I tried imp/test.php and that is working fine, same if I do not use IMP to login to Horde frame work, but just the standard login using imap.
