Question Warnings in mail log [SASL LOGIN authentication failed]

andrecab93

New Pleskian
Server operating system version
Ubuntu 22.04.3 LTS
Plesk version and microupdate number
Version 18.0.58 Update #2
I check this information in the email logs several times:
2024-02-02 13:23:14WARNINGpostfix/smtpd [3512567]warning: unknown[IPXXXX]: SASL LOGIN authentication failed: authentication failure
2024-02-02 13:23:14WARNINGplesk_saslauthd [3512587]failed mail authentication attempt for user '[email protected]' (password len=9)

2024-02-02 13:22:37WARNINGpostfix/smtpd [3512567]warning: unknown[IPXXXX]: SASL LOGIN authentication failed: authentication failure
2024-02-02 13:22:37WARNINGplesk_saslauthd [3512569]failed mail authentication attempt for user 'glendali' (password len=9)

and so on, does anyone know how to solve it? I already have fail2ban activated but it's still there, is that normal?
