I've checked the forward and reverse lookup zones, and as far as I can tell there is nothing wrong there. I have restarted SMTP, IIS, and all other services related to email, I've flushed and registered the dns. My server has a static ip of: .xx ip 255.255.255.0 subnet .1 default gateway 64.59.135.xx dns2 64.59.135.xx dns2 the 2 dns addresses are the dns of the ISP, should they be the ones from or should they be something diffrent? I've tried everything I can think of to get smtp working. The dns records and mx records were created using and the domain records (on ) were updated to reflect the editdns servers. I don't know if it is a dns issue because thier website can be accessed fine (and the website is residing on the same server as the emails)(both are part of the default website in iis). When I look in the message tracking properties this is what I see for any outbound emails: SMTP Store Driver: Message Submitted from Store SMTP: Message Submitted to Advanced Queuing SMTP: Started Message Submission to Advanced Queue SMTP: Message Submitted to Categorizer SMTP: Message Categorized and Queued for Routing SMTP: Message Routed and Queued for Remote Deilvery and that's where it gets stuck, it never reaches the destination. This has been going on for a week now, but it seemed to mysteriously fix itself on Monday, but then on Tuesday it was back to not sending emails. All the users can receive external and internal emails, but none of them can send emails to anything outside the organization.
I'm have a huge problem with exchange server emails.
