Sorry haven't seen your message bevor...



mbstring and iconv are compilled in my installation.



These are some modules presents in my compilation options :



bz2,db4,curl,dom,freetype,png,gd,gettext,ncurses,gmp,iconv,jpeg,openssl,pspell,xml,zlib,bcmath,mbstring,mbstr-enc-trans,pear,imap,imap-ssl,kerberos,ldap,mysql,pgsql,unixODBC,mcal

No feedback.

*Still* can't reproduce this.  No matter if I create a folder on the 
folders screen or via the "Create new sent-mail" interface.



Do you have both 'iconv' and 'mbstring' built-in to your PHP installation?

Tryed many things but still this message...



Le dossier « ?l?ments envoy?s » n'a pas été créé. Le serveur a 
répondu: Can't create mailbox name with 8-bit character

   Message bien envoyé, mais non enregistré dans ?l?ments envoy?s



Tryed, with writing the folder name in "horde/imp/config/prefs.php" 
for the sent_mail_folder :



$_prefs['sent_mail_folder'] = array(

     'value' => 'Éléments envoyés',

     'locked' => true,

     'shared' => false,

     'type' => 'implicit');



and tryed letting the user choose is sent_mail_folder, but the message 
was the same when using such named folders...



But when i tryed to move/copy a mail from one folder to a such named 
folder, all is ok.

Works fine here (I am using dovecot).  We encode the names of folders 
in UTF7-IMAP so there should be no 8bit characters being sent to the 
mail server.

When i try to set the "Sent Items" folder or the "Deleted Items" 
folder to a french name (accentuated name), i get the following 
message when i try to delete a mail:



The folder "?l?ments supprim?s" was not created. This is what the 
server said: Can't create mailbox name with 8-bit character



The names for this 2 special folders were "éléments Supprimés" and   
"éléments Envoyés"



(Trying to connect an IMP server to an Exchange 2K server (in French)



Thanks for all.
