Hi, I need help as I am getting multiple hits on dovecot_login authenticator failed. My Inbox is full of messages such as Time: Sat Jan 21 19:52:50 2023 +0530 IP: 80.68.125.160 (SE/Sweden/80.68.125.160.karlsborgsenergi.se) Failures: 1 (smtpauth) Interval: 3600 seconds Blocked: Permanent Block [LF_TRIGGER] Log entries: 2023-01-21 19:52:46 dovecot_login authenticator failed for (80.68.125.160.karlsborgsenergi.se) [80.68.125.160]:48636: 535 Incorrect authentication data (set_id=business) Is there any option to reduce or harden the security to avoid such massive emails? I am new to centos and have difficulty dealing with this issue.
