Salut,

Primul mesaj nu este de eroare, este un return receipt. Cine trimite email-uri sa-si scoata din clientul de email setarea respectiva, daca ii incurca.

Al doilea mesaj nu se vede bine (lipsesc bucati din el), dar noroc de log-uri pe server :

2021-02-15 16:23:50 1lBbj3-00058G-Ih H=alt3.gmail-smtp-in.l.google.com [142.250.4.27]: SMTP error from remote mail server after RCPT TO:<ingfratar@gmail.com>: 450-4.2.1 The user you are trying to contact is receiving mail at a rate that\n450-4.2.1 prevents additional messages from being delivered.

The user you are trying to contact is receiving mail at a rate that prevents additional messages from being delivered.

In traducere, pe adresa ingfratar@gmail.com <mailto:ingfratar@gmail.com>, vin prea multe email-uri (din diverse locuri). Google nu le primeste pe moment, zice sa reincercam mai tarziu. Asta face serverul automat timp de cateva zile.

In concluzie, sunt 0 probleme.
