Hi guys,

I'm having problems with the exchange server version 6.5 running on Windows 2003 server. My clients have received a bulk of email indicating bounce backs that have occured about a month ago. It indicates emails that couldn't be sent to a recipient. However some of my clients say that the emails have been sent even though they received a bounce back a month later. I then found out that one of the main administrators have done reboot of the exchange server which was the reason why people have received these bounce backs a month later. It was sitting on the queue all the time and when the reboot was done it sent out all the bounce backs at once to the users, and all the sent mails that were stuck on the queue were also finally sent . What I want to know is why they have been sitting there for so long and why it doesn’t sometimes send the bounce back. It seems to just sit there and also the emails that are sending out are just being trapped inside the queue. What might be the problem?

Check the MX record, I think it maybe something to do with that.

Also be sure to setup a PTR record for each of the clients with their respective ISP. (I.E. call and ask Verizon to make a PTR record for the static IP you rent from them as "'mail'.example.net" where 'mail' is the DNS name of their exchange server and 'example.net' is the client's url.
