Hi all, My previous message indicated that I was getting a delay on outbound messages. I have since noticed that the delay was due to messages being blocked up in the queue (Thanks Carl). I have also noticed that all the messages that are blocked are either from "System Administrator" or a blank sender. What is this all about???? When I delete the messages all works fine for about a day or so..but then I have to go back and delete them all again with 24-48 hours. Thanks
