Visit www.canyouseeme.org and test port 25.  If you don't get SUCCESS, check your firewall hasn't lost it's configuration and that port 25 is open and forwarded to your server.

Is it possible a service got hung and the server needs another reboot?

Is the domain in the accepted domains per this thread?

Simplify Active Directory Administration

Administration of Active Directory does not have to be hard.  Too often what should be a simple task is made more difficult than it needs to be.The solution?  Hyena from SystemTools Software.  With ease-of-use as well as powerful importing and bulk updating capabilities.

- was the power failure only for this server or other servers also.

If for other servers also.. you may require to reboot your server as DC and DNS may not have been booted and exchange is not in a proper situation..

Can you divulge your domain name - it will make life easier to check.  I can also hide it for you once posted.

Very weird!  I get the following too:

The Microsoft Exchange POP3 service is ready.

Seems that you have port 25 mapped to port 110

Check the Queues and send the error message received.

Run command on EMS; get-queue |fl

bill_lynchCommented:
your email is probably getting queued somewhere.  Is there anything upstream, i.e. an email appliance for spam filtering that receives the email first that may be having issues?  How about a firewall?  Anything else get affected by the power outage?

Are you sure that mailbox store is in mounted state..?
if not use Eseutil/mh and check the status once.
If in mounted state check the mailflow connectivity using testexchangeconnectivity.com.

Check the default receive connector settings, permission and authentication.

Alan HardistyCo-OwnerCommented:
Please check your firewall and make sure that port 25 isn't getting redirected to port 110.

What sort of firewall do you have?

interesting , I went to reboot the machine and it said it had 1-54 updates to install ? As as its finished I'll pull the info requested and check the permissions..

Just really weird how a power failure would cause all this grief, it on a battery backup outage was for 40 minutes...

Sonicwalls are what I use, the ports are correct, i should be pointing to port 25 correct ?

Alan HardistyCo-OwnerCommented:
Yes - port 25 should be open and forwarded to port 25 on the Server.

What does:

netstat -anbp tcp | findstr :25

show from a command prompt on your server?

No probs - worth a reboot afterwards and then see if it has rectified itself.

Random - but possibly not permanently fixed, but for now - I am glad your mail is flowing.  Might be a POP3 config issue.  If you need POP3 - and it screws up your mail again - do shout.
