Thanks … [View More]

[Dovecot] RFC 6154: German umlauts in special_use folder names
by Daniel Parthey 17 Sep '12

17 Sep '12

Hi, the Drafts special folder is called "Entwürfe" in German locale. How should the special_use entry in the config file look like? Would you recommended to use the encoded folder name... mailbox "Entw&APw-rfe" { special_use = \Drafts } ...or rather the utf-8 Encoding in the dovecot config file? mailbox "Entwürfe" { special_use = \Drafts } Regards Daniel -- https://plus.google.com/103021802792276734820
