I've built a mail server and I wanted to include Spamassasin. As noted above, the machine is running Ubuntu Server 23.10, so I started with
sudo apt install spamassassin spamc but I can't start the spamassassin.service; the error message I get when I run sudo systemctl start spamassassin says "Failed to start spamassassin.service: Unit spamassassin.service not found." Spamd, however, is active and running. Is this normal? If it isn't, what can I do to correct things? Further information available on request. Thanks in advance! Ken
