In addition to that first line, it also says:
make sure SMTP Virtual Server is running in Internet Services Manager
check the event log for SMTP Service events
turn on logging for your SMTP server, to see if the mail is even being
attempted to be sent to the server
make sure your smarthost and FQDN are configured correctly
make sure your smarthost allows you to relay unconditionally (some
require authentication)
make sure your server can resolve the ip of your smarthost name - try
using the IP of your smarthost to see if this is the issue
restart the SMTP Service (or IIS altogether), and if that fails reboot
the server, to see if this clears up the backlog
make sure you are sending from / to a valid address / domain
check any .rtr files in the \queue\ folder - these can be caused by
various mistakes in code or config
check the server itself by setting up outlook express on the machine,
using the same settings, and attempting to send mail
if the machine is behind a firewall/router, make sure it has access to
port 53
you might also check any 3rd party software; e.g. one user had Kerio
running on his server and, to prevent spam by his users, it was
limiting the SMTP server to 20 messages per hour... anything over this
would sit in the queue until the next hour
make sure that your disk has enough space to hold the messages; one
reader wrote in that they had this problem when they were using a
smart host, and the smart host had a full C: drive... so make sure to
check for problems on all machines in the chain
Did you do those?
