[Dovecot] German Umlauts in folder name and sieve

27 Dec 2013


      Hi,
I had created an imap folder that has German Umlauts in it:
„RA Rößner - Merle“
When finished, the result looks like this on filesystem:
drwx------  3 vmail vmail 4096 Dec 27 11:02 RA Ro&AwgA3w-ner - Merle/
I wrote this sieve script (with SOGo):
if anyof (address :regex "from" "@.*\\.ra-roessner-merle\\.de") {
fileinto "RA Ro&AwgA3w-ner - Merle";
stop;
}
That creates a new IMAP folder with exactly this strange name.
Can I change this somehow?
