Recently I tried to send a message using the SMTP method with several ports, among them I tried to use port 25 465 587.
However, when trying to run these errors occur
May 1 03:52:13 localhost postfix/smtps/smtpd[25282]: connect from gateway[10.0.0.1]
May 1 03:52:52 localhost postfix/anvil[24974]: statistics: max connection rate 4/60s for (submission:206.168.34.189) at May 1 03:49:32

May 1 03:52:52 localhost postfix/anvil[24974]: statistics: max cache size 1 at May 1 03:49:25
Note: Don't judge me, I'm learning little by little. and I would like you to help me with this
