Cannot Receive or Sent External EMails

By jwailyo ·
Hi there,

I have a problem with my email service (External)....

I have Win 2003 Server and Exchange 2003. I also have a proxy as my firewall. I have direct SAT via STP singapore. Upon a recent Routing Issue, my Internet service was restored and External Email Service never restored. My Internal EMail is ok. I cannot sent and Receive Emails externally.

When I use MXToolBox and use Mail Diag, it displays error msg "Reverse DNS FAILED! This is a problem''.


Can anyone please help...

Try reposting this in the 'Q&A' forum. The 'Discussion' forum is for matters of general discussion, not specific problems in search of a solution. The 'Water Cooler' is for non-technical discussions. You can submit a question to 'Q&A' here:

http://www.techrepublic.com/forum/questions/post?tag=mantle_skin;content

There are TR members who specifically seek out problems in need of a solution. Although there is some overlap between the forums, you'll find more of those members in 'Q&A' than in 'Discussions' or 'Water Cooler'.

Be sure to use the voting buttons to provide your feedback. Voting a '+' does not necessarily mean that a given response contained the complete solution to your problem, but that it served to guide you toward it. This is intended to serve as an aid to those who may in the future have a problem similar to yours. If they have a ready source of reference available, perhaps won't need to repeat questions previously asked and answered. If a post did contain the solution to your problem, you can also close the question by marking the helpful post as "The Answer". .

But in the meantime what changes did you make to restore the Internet Connection and why where they necessary?

Basically what happened that required you to change things?

List everything when you repost as a Question and someone here should be able to help you.
