Hi Matt, > What could be the cause of this I wonder? The server doesn't seem massively busy in between those times.
In my opinion, something could be wrong with your SMTP remote gateway that makes James (here RemoteDelivery mailet) can not send mail outbound right away. Then, RemoteDelivery would delay some time before retrying the next remote delivery, which could explain the delay time you observed. You can send an inbound email to verify the theory. If inbound is fast, then the problem is likely at the SMTP remote gateway.
