works great, thanks.

Well that's embarrassing.  We've been searching for '/' as the escape 
character instead of '\' for at least a year.  Luckily, most IMAP 
servers use literal strings instead of quoted strings.  Anyway, this 
has been fixed.

Changes have been made in Git for this ticket:

Bug #8767: Search for correct quote escape character

http://git.horde.org/diff.php/framework/Imap_Client/lib/Horde/Imap/Client/Socket.php?rt=horde-git&r1=63abbc013833b294650742b7c7b3d089c51fd4af&r2=a2aafe63cc6354096d7ea22a2e25a8e009e68d9f

Ah, I wasn't aware of this info. Is it possible to add a comment about 
this in imp/docs/INSTALL ?
I've attached the imap log when opening message email2.elm
we use courier-imap-4.3/php-5.2.11

I have an old cvs copy (07 oct 2008) of Horde/IMP and I don't have any 
issue opening those messages.

This indicates that there is an issue either with your IMAP server, or 
with the way we are parsing the IMAP data.

To further debug this issue, we need details of the IMP -> IMAP/POP 
communication.

To enable debugging, see instructions contained in 
imp/config/servers.php (the 'debug' config parameter).

Debugging should not be enabled on a production server,   Attach/post 
only the portion of the log that directly deals with the problem 
reported (it may be simplest to clear the log file and then perform 
the event that causes the error).

I can't read the subject of email.elm as it is encoded, but I'm pretty 
sure it is the same issue.

I've attached a screenshot of what it looks like. It seems that IMP is 
having trouble processing the subject.

I've added a print_r($ob) in imp/mailbox.php line 731 (just before the 
try[flags]) and here is the output for email2.elm :

cache is disable, and I clear /tmp folder all the time.

using email2.elm, If I reformat the subject header (see below), 
warning/error is gone.
-- Subject: Re: Nouvelle Offre commerciale "Busines
++ Subject: Re: Nouvelle Offre commerciale Busines

Works fine here.  You might want to try clearing the imp imap cache, 
if using that.  Or else check to see if your IMAP server is returning 
bad information.  Otherwise, you will need to debug yourself and 
provide information on what these variables are actually set to on 
your installation.

I've attach a second email. I'm getting different errors with this one :

** IMP messages list  :
