I changed my server name, but Spam assassin keeps the old one (that I kept valid anyway).
I did not found any setting for this, and when I try to edit the config file, Webmin says "Invalid config file.
This file (etc/spamassassin/local.cf) exists at the correct location, but it is all commented out. It has no option to configure such a thing.
This is a minor issue, but my email headers show this server name beside the smtp one.
