    It might be that someone tried to connect with an SSL protocol that's too old or someone tested your server for vulnerable protocols. If the mail system is working fine besides having these errors in the log, I would just ignore the error.

    I see.
    Everything was okay, so far, there was no problem with email.
    Thank you!
