Er, I don't get it, you issue

ls "Maildir/.Travail.Linux.Arch Linux/cur/"

and you get the error:

ls: ne peut accéder Maildir/.Travail.Linux.Arch
  Linux/cur/1224250603.M73770P8724.gen0:2,: Aucun fichier ou dossier de ce
type

(you've translated into in the other post: no such file or directory)

??

If so, I would:

a) check for dangling symlinks,
b) check for funny characters in the name ".Travail.Linux.Arch Linux", 
e.g. line break, tab, ...
c) umount / mount the file system if remote, to reset the internal cache
d) make a file system check

Otherwise, I suppose you should chdir into "Maildir/.Travail.Linux.Arch 
Linux/cur/" and perform ls -ld 1224250603.M73770P8724*
Because Timo's usually very descriptive error messages would lead me to 
think that the directory entry is either not accessable, but visible (e.g. 
dangling symlink, read ACL* but no rename ACL, or some other restriction), 
or that indeed there is such entry, but something is causing it to change 
some attribute, like keyword, state, etc. everytime, e.g. by by two 
simultaneous connections.

* With ACL I mean something other than plain Unix permissions, like POSIX 
ACL, AFS perms, NFS readonly, mandatory locks, SELinux, AppArmor, .... .

Bye,
