Hi, In my case, I have upgrade to IspConfig 3.2.8p1 (on Debian Bullseye) There is no set any email forwarding (on the web configuration page), but it still forwarding emails to 2 other mailboxes, as before upgrade, and it not necessary anymore. One email is in alias domain, the other one is outside domain (gmail). This problem is belong to only one mailbox. How can I disable the forwarding? Where can I find? In postfix or dovecot service?
