Exchange down?

[RichB]

Afternoon,

 

Running exchange 2007 on a 2003 R2 box

 

this is what is happening:

 

Internal to internal email fine

Internal to external email fine

External to internal not delivering

at home logged on through the OWA to internal mail fine (so line issue)

 

Nothing at all has changed on the server, uninstalled the anti virus and spam filter. Rebooted. No message que appearing

 

ANY IDEAS PLEASEEEEEEEEEEEEEEEEEEEEEEEE

[mtillbrook]

could be an MX record problem? have a look at mxtoolbox.com and run some tests perhaps?

[glennda]

try running this - https://www.testexchangeconnectivity.com/

 

does the external user get a bounce?

[RichB]

all tests came back ok? But there not......

on inbound smtp? If you open the exchange management console and go to toolbox and queue viewer do you see them sitting there?

 

And does an external user get a bounce?

Plenty of space on the server? Re-start SMTP service.

If the external connector is saying SMTP is functioning then its more likely to be Microsoft Exchange Transport.

1. Up the protocol logging on the Receive connector for the internet mail and check if it's hitting your Exch server.

2. Send a test message and use MT to see if was accepted & routed & delivered.

3. Maybe describe your topology for routing in more detail. Firewall/NAT/

4. Any changes made?

5. Post RCA results from SMTP tests (Inbound).

Internal changed to Internet

on 2nd looks Sorbs has us on a blacklist could this be what the answer is?

 

Plenty of space, re-started SMTP, external client gets a bounce back saying timed out,

[RichB]

Yes please post the NDR removing any confidential information. Put your IP/Domain into here Blocklist Removal Center - The Spamhaus Project and it will give you info. If you happy PM me the info and I'll dig through it.

You still need to establish why you are blacklisted

We found Exchange 2010 needs a percentage of space left. We had this issue and had 2.5GB free on hard drive but could send internal email and send without issue.
