It's ok that ClamAV and Amavis are using a lot of CPU for a short time after install and also after a server reboot. Memory usage is fine too. Normally you assign to a complete hosting server with mail, web, database, FTP, and DNS at least 2GB ram, you assigned just 1GB, so it is to be expected to get 100% RAM usage in your case.
I have a small server. Overall, I have 8GB. Now I have increased RAM to 2GB. I always feel that the clamd consumes a lot of RAM
Yes, ClamD uses a lot of RAM. If you don't have enough RAM and not many email traffic, then you can try to stop the CalmAV daemon so that amavis will use a fallback to clamscan which is started on demand when an email arrives.
Try: systemctl stop clamav-server and then check if mail system still works. If yes, you can disable the service permanently
This doesn't work Code: root@ispconfig:~# systemctl stop clamav-server Failed to stop clamav-server.service: Unit clamav-server.service not loaded. root@ispconfig:~# systemctl status clamav-server Unit clamav-server.service could not be found.

That's the webmial client and not mail in general. It works fine when using one of the official perfect server guides, the autoinstall script you used is not from ispconfig, so can't say if it fully works. Might be that webmail is here: http://192.168.1.107/webmail or http://192.168.1.107:8081/roundcube or that the script that you used does not install a webmail client at all.
In my first post: here's cat /var/log/ispconfig_setup.log https://textuploader.com/1d4lr Look at the end Code: ... Installing Webmail client (Roundcube)... Installing Webmail client Plugins (Roundcube)... [DONE] ... You will need to edit the username and password in /var/lib/roundcube/plugins/ispconfig3_account/config/config.inc.php of the roundcube user, as the one you set in ISPconfig phpMyAdmin is accessible at: http://ispconfig.com:8081/phpmyadmin or http://192.168.1.107:8081/phpmyadmin Webmail is accessible at: http://ispconfig.com:8081/webmail or http://192.168.1.107:8081/webmail
