[imp] authentication problem in log files

[Bernard Paris]

I gest this is the same problem I posted on 16 oct 2001, "imapd Login 
failure from IMP":

Althought IPM, Horde and all the webmail features work all very well, 
I always get strange login failure messages in my imapd logs, coming 
from IMP accessing imapd:
Oct 15 14:48:52 guppy imapd[24717]: Login failure user=\200�)^H 
host=guppy [127.0.0.1]
Oct 15 14:48:55 guppy imapd[24715]: Login failure user=P')^H 
host=guppy [127.0.0.1]
I'm afraid this will become worst when hundreed of users will access 
the IMP server.
here are things I use:
    redhat7.1 - kernel 2.4.9
    horde-1.2.6
    imp-2.2.6
    php404pl1
    mysql-server 3.23.32
    mysql  Ver 11.12 Distrib 3.23.32
    imap-2000c-10


I got this following suggest from Anil Madhavapeddy <anil@recoil.org>:
------------
Upgrade your version of PHP4 to remove a buffer overflow,
or just apply this patch to your php-4.0.4pl1 code and recompile
that:

http://www.horde.org/imp/contrib/php-4.0.4pl1-imap-patch.txt

but I not have been trying since my php comes from 
php-4.0.4pl1-9.i386.rpm package and upgrading to php-4.0.6.i386.rpm 
implies lots of other changes.

I'm still thinking now on what to do with this......
