Thanks Brian & Mark for your quick response! The recipient is a remote destination. It is being initiated from a relayed domain for my email server to a remote mail server / destiniation. I will watch and see if it does eventually go through. If I no longer see the entry listed in postqueue -p, how do I know if the message was sent successfully of just failed and cleaned from the queue by the queue manager?
