When attempting to send emails, the error ‘waiting for spool enumeration’ occurred. How can this issue be resolved?
Well a bit more information would be handy… have you been using the kumomta already for sendouts? If so then all pending mails and webhook requests that still need to handled are stored on disk. And usually that storage will be checked and read if you restart kumomta.
But this should be sorted after a few minutes after restart… but if you have over 100k items in the queue then it can take a bit more then a few minutes.
