My server was infected to a malware. That malware sent lots of emails to random people with random content (promotional content). And now, my domain authority is getting pretty low and every email I send goes to spam.
What I said is a guess (though I'm sure about that malware, but I'm not sure it has sent emails). Anyway, is there any log file or whatever similar contains a log of all emails that are sent from my mail server? If yes, where is it located?
Thanks in advance.
