It seems the maildir implementation is different in akonadi as compared to dovecot (and standard maildir).
Consider a mail folder structure:
fol1/fol2/fol3

When creating this in kmail under local folders (i.e. a local akonadi maildir resource), the directory structure on disk is as follows:
fol1/{cur|new|tmp}
.fol1.directory/fol2/{cur|new|tmp}
.fol1.directory/.fol2.directory/fol3/{cur|new|tmp}

In dovecot (and standard maildir) the directory structure is as follows:
.fol1/{cur|new|tmp}
.fol1.fol2/{cur|new|tmp}
.fol1.fol2.fol3/{cur|new|tmp}

There is no nested directory structure on disk and mail (sub)folders are indicated by a dot in the filename. I have noticed this before and it is an incompatibility that prevents simple copying from a dovecot server to a local akonadi maildir resource. Anyone know the reason for this difference? The dovecot implementation seems cleaner.
