Postfix – how to retry delivery of mail in queue?

According to postqueue(1) you can simply run postqueue -f to flush your mail queue. If the mails aren’t delivered after flushing the queue but are being requeued instead, you might want to check your mail logs for errors.

Taking a peek at postsuper(1) might also be helpful. Maybe the messages are on hold and need to be released first.
