This problem can be worked around (if configuration allows this) by changing:
mail_attribute_dict = file:%h/dovecot-attributes to e.g. mail_attribute_dict = file:/path/to/mails/%d/%n/dovecot-attributes This avoids missing %h value. Bug can be closed. NOTE: Examples in dovecot documentation all use: mail_attribute_dict = file:%h/Maildir/dovecot-attributes This triggered the error I've observed. -- Robert Senger <robert.sen...@gmx.de> PGP/GPG Public Key ID: 8714E1A3
