Which dkim software is used by ISP? I saw OpenDKIM but I didn't find it on the server created on the base of Perfect Server tutorial.
You do not say what operating system you run. On ubuntu and debian, Code: dpkg --list | grep -i dkim shows what DKIM software is installed.
Yea, right. Ubuntu 16.04. Btw thank you for answer and command. It shows libmail-dkim-perl 0.40-1. Thank you for answer. Without ISP it would be automatically configured/enabled and ready to set DKIM record in DNS?
ISPConfig generates the DKIM record and adds it to the mail and DNS system (when the zone is managed in ISPConfig). If the zone is managed outside of ISPConfig, then you have to add the DNS TXT record that is shown in the email domain settings at your external DNS server.
Thank you for answer. I asked wrongly. I mean does the amavisd-new installation provides automatically configuration of dkim and I need to do only one thing - set DKIM (yes, it is TXT) record?
Yes, having an option to enable and configure DKIM in ISPConfig would not make much sense otherwise You should really consider reading the manual.
