Ever since postscreen is up and running I see very often from various IPs this:
Jul 26 20:05:25 mx postfix/smtps/smtpd[20590]: too many errors after AUTH from unknown[109.167.202.37] Jul 26 20:05:25 mx postfix/smtps/smtpd[20590]: disconnect from unknown[109.167.202.37] ehlo=1 auth=0/1 commands=1/2 Jul 26 20:05:31 mx postfix/submission/smtpd[20597]: too many errors after AUTH from unknown[109.167.202.37] Jul 26 20:05:31 mx postfix/submission/smtpd[20597]: disconnect from unknown[109.167.202.37] ehlo=2 starttls=1 auth=0/1 commands=3/4 Jul 26 20:05:36 mx postfix/smtps/smtpd[20600]: too many errors after AUTH from unknown[109.167.202.37] Jul 26 20:05:36 mx postfix/smtps/smtpd[20600]: disconnect from unknown[109.167.202.37] ehlo=1 auth=0/1 commands=1/2 Jul 26 20:05:42 mx postfix/submission/smtpd[20605]: too many errors after AUTH from unknown[109.167.202.37] Jul 26 20:05:42 mx postfix/submission/smtpd[20605]: disconnect from unknown[109.167.202.37] ehlo=2 starttls=1 auth=0/1 commands=3/4 Is there a way to deal with them?
