Hello, at first, i'm using howtoforge and ispconfig for years now on my private servers, its a great job you are all doing here. Yesterday i setup a new server to replace my old one. I used the howto The Perfect Server - Debian 10 (Buster) with Apache, BIND, Dovecot, PureFTPD and ISPConfig 3.2 (howtoforge.com) The server is running fine and working normally. After reading some new features in ispconfig i checked and enabled some more safety features like DKIM or SFP. I also found out that it is possible to use a delimiter "+" for my emails, this is a great feature i didn't knew until now. But now i aks if and where it is possible to change the recipient_delimiter from "+" to another one. In the /etc/postfix/main.cf i found the delimiter and changed it. But after that the emails are not delivered to the mailserver. It is only working for the "+" when i change it back. I found out / read that there is also the delimiter in dovecot, but all i found where disabled entries: I also didn't found this in the settings in ispconfig panel. All i know is that dovecot is only working with "+", but where can i change this. Also i read that dovecot should only be able to use 1 delimiter, not like postfix several ones. Is this still true or can dovecot use more delimiters in the actual version?
