    Try talking to your ISP about port 25. Some nasty ones will only allow it with a business line.

    The other hack attempts are the usual hack attempts. One of the joys or running a public facing server. The only reason for you to leave port 465 or port 587 open is if you want to send mails from your e-mail client via your server when you are external to your LAN

    I was able to talk to my ISP to open up incoming port 25! But I'm still not getting any mail that I can see. Here is the nmap showing the port open, but I'm still getting rejection messages from gmail and protonmail.
