When watching my logs, I see tons of login attempts for non-domains. like user@199.84.XXX.XXX (my server's IP) vs. a domain. I know they are all bogus. Is it possible to just straight up not accept logins for these? Maybe an IP Table rule? It really fills up the logs.

Maybe establish the pattern and create a fail2ban rule.
