imapd Login failure from IMP but IMP works

[Bernard Paris]

I use horde-1.2.6 with imp-2.2.6 on a RedHat7.1 box, php404pl1.

   All things seem to work fine, but I find many "Login failure" errors in file 
   /var/log/messages, like:

   Sep 10 12:45:41 guppy imapd[12762]: Login failure user=\220| <^H host=guppy 
   [127.0.0.1]
   Sep 10 12:45:47 guppy last message repeated 2 times
   Sep 10 12:55:52 guppy imapd[12780]: Login failure user=0:3^H host=guppy 
[127.0.0
   .1]

   These come from IMP using IMAPd.
   Do you know excactly what it is and what are those strange users ??
