i will look Fail2ban, to see if i can install it.
Fail2Ban should already be on your server Rodrigo. I also get the same logs. It is spam servers trying to find holes in your server to send spam. If you notice they are warnings. They should also be being blocked from multiple attacks from one of the routines I installed on your server. You should be OK.
I'll take a look tonight.
