Hi. We have some IDN domains like: webåäö.com When creating in ispconfig we use: xn--web-slae7h.com Website work. But email is different. In /var/vmail two folders is created, one /var/vmail/webåäö.com with content, and one empty /var/vmail/xn--web-slae7h.com Due to this we get alot of warnings email (cirka 20) like: 05.03.2019-11:19 - WARNING - Action aborted, file is a symlink: /var/vmail/webåäö.com Also you cant change spamfilter for domain, probably same error that webåäö.com is used, when it always should use xn--web-slae7h.com for files. Activate DKIM does not save the DNS TXT record either. Probably a bug.
