I have a MS Server 2003 w/SP1 and Exchange 2003 w/SP2. I have recently upgraded my GFI Mail Essentials to version 10 and have noticed that my e-mails are getting built in in the messages pending queue. Does anyone know a tool or something I can use to track this problem down. I do get event id 4004 and 4015 when I restart the machine. These have been going on for 6 mo (before I was here at this job) and they didn't have mail delivery problems then. Thanks in advance for the help.
