How to change the default DKIM selector

[miaber]

Yes, it was later discovered that if only change /etc/opendkim/KeyTable, this will not last for a long time, it will automatically return to the mail selector
Therefore, we need to create a new file /etc/opendkim/KeyTable_new：

example.com example.com:box:/home/user-data/mail/dkim/mail.private

1. Any idea what is overwriting /etc/opendkim/KeyTable?
2. If we use /etc/opendkim/KeyTable_new, will it reflect newly added domains?
3. Will these changes persist after an MIAB update?

I have an issue here and GMail is complaining my DKIM fails

Suppress/re-classify MX errors

This domain’s DNS MX record is incorrect. It is currently set to ‘10 mail.example2.com’ but should be ‘10 box.example.com’. Mail will not be delivered to this box. It may take several hours for public DNS to update after a change. This problem may result from other issues listed here. I would like to use MIAB as a send only server, so my MX record is configured differently to what MIAB expects and is causing MIAB to report the error above. Can I make MIAB suppress/re-classify the above erro…
