Also if you enable logging of your smtp interface events (to maximum or so)
your event viewer should give you a pretty good picture of who is connecting
to your exchange and otheer usefull infor for troubleshooting

Could be a couple of different problems.


1. Some one is relaying through your server and consuming all the SMTP
threads available.

2. There are sessions stuck open.

3. Disk space.

4. Maximum database size.

5. DOS attach.

6. Server is relaying out lots of virus messages from internal computers.


There are probably a few more.

Hi All,


When I try telnet into my Exchange server at port 25, I got this error

421 connection limit reached


I am using Windows NT4 and Exchange 5.5. 


Currently I cannot receive any mail. Please advise.



Best Regards,
