Afternoon,

I have been going around circles trying to resolve this. I have an exchange server 2003 that can receive emails but cant send out. late last week, we had 47000 spam emails that could not be sent and had the queue cleared and now nothing appears in the queue when an email is sent and no external users receive emails from this server.

Have you checked the message tracking when sending a test email? Any bouncebacks from the server at all?

I would use the Message trackers as suggested by Jay above. Also I would ensure to see that your domain isn't blacklisted on one of the SPAM lists, as many companies now use these lists by default to filter incoming traffic. Also I would check to see if you can send email internally.

Go to www.mxtoolbox.com and validate that your server is not on a block list as well as reverse-DNS records are fine.  Check your connector on Exchange and validate there are no errors in logs.

You mean your internal mail flow is working fine and only you have problem with you external email and when you send a mail it not appear in queue for remote delivery.

As all above user suggest you for message tracking  will give proper picture to check further
 You have not given information that your exchange server is internet facing for sending email or using  Smart host

Spamming will empact on outbound email delivery but not for all email and you will get bounce back

If you facing this issue after clearing spam queue  most import how you did that you did anything with   queue .
Basically you can stop SMTP  service and rename the queue  and start the SMTP service it will create new Queue  and you can check

Dumb question.  Since that massive mail queue flood, have you rebooted this server?  If not, please do so.
