You can dig the UTF8 hostname, they are valid for query.
Hello buddies,
I just want to make some simple filters for outgoing messages.
for example, the message content has some keywords (like "VPN sale")
included, it will be rejected by the system.
I know there are the software Rspamd and Spamassassin, but they are too
heavy for my simple usage.
