This error occurs after the backup is completed
“MailKit.Net.Smtp.SmtpCommandException: 4.7.1”
How can I eliminate this problem?
The same settings work fine in Windows Pro or Windows Home. However, the above error message pops up on Windows Server 2019 (2 units).
I tried changing the --send-mail-url= option without success.
I found the reason, because the mail server is set with a maximum daily number of mails, and the number of mails has been reached when setting up the windows server. In fact, it has nothing to do with whether it is a server or not.
