After I made a change to my DNS server for "recursion no;" queue mail delivery has increased considerably. Do not know if it was coincidence but the delivery of mail is very slow. What could I do to improve this performance check or to improve the delivery? because the local network with about 400 emails retained in the queue.
Best regards,
