exchange 2010 server stop receiving emails after power failure

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?

i show success

- 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..

interesting when I telnet using port 25 I get the response below not sure if this is correct  

+OK The Microsoft Exchange POP3 service is ready.
-ERR Connection is closed. 12

its the only server, everything on the exchange side works calendars, send email, even the active sync on my iphones. I just cannot receive an email from the outside. it has worked for over a year with no issue...  very puzzled..

Are all your Exchange Services started and all other Automatic Services?

All but three
MS Exchange monitoring
MS exchange IMAP4
MS exchange Server back up

these are now running no change

if, i send a email to my exchange server address from an external source I get no bounce back, or delivery error which is strange ...

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

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.

Ohh sorry i didnt read it fully.
can u post the test results here.

Check the default receive connector settings, permission and authentication.

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 ?

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?

waiting on updates to complete, i7 server with 16 GB ram taking forever..

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

ok server back up.

took the router out of the picture here, open a telnet session on a client computer in the same room, telnet to the servers ip address port 25 and got the same response ?

the pop services is now stoped

Woooooooooooooooooooooo Hoooooooooooooooooooooo pop service off email is flowing !!!

what the heck happen!!

Alan thank you for your help , you solve this issue.. thank you for your patience as well
you Rock!

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.
