Recently my primary Exchange 2000 mail server started having significant delays (5-20 minutes) in the (Remote delivery) queue to an Exchange 2000 server in another site. &nbsp;We would see the queue start to fill up with messages and seemed to release them on a schedule, though I couldn't pin that schedule down. &nbsp;This impacted both internal and external messages. &nbsp;One of the things I stumbled across was that the AD site link to that remote site had both the IP and SMTP protocols added under &quot;This server is a preferred bridgehead server for the following transports&quot;.<br />
<br />
Is it likely this had anything to do with the delayed message delivery? &nbsp;I do not know if an administrator mistakenly added that protocol recently.<br />
