A external send to my Exchange 2010 server occaonally bounced back with the following message. eg. The external sender send 5 messages to me and I can only receives 2.

I also test my email using the web http://www.verifyemailaddress.org. It sometimes says "We feel that xxxx@xxx.com is valid", and it sometimes say "We feel that xxxx@xxx.com is not valid". Have any idea ? Any advise on the problem is apprecated.  Thx


This is a delivery failure notification message indicating that an email you addressed to email address :
-- xxxxx@xxxxxx.com

could not be delivered. The problem appears to be :
-- Recipient email address is possibly incorrect

Additional information follows :
-- Transaction failed

What MX records do you have against your domain? If you are unsure how to check this please go to mxtoolbox.com.

Does your email address have any special characters or is it just alphanumeric?

All passes for Inbound SMTP.

For Outbound SMTP, it say I don't have SPF record. Will that cause the external sender not able to send to our Exchange. However, the message is " Recipient email address is possibly incorrect"

SPF records affect outgoing only (although if the sender has SPF issues then you may have issues receiving emails but it wouldn't in this form)

MX record point to our anti-spam gateway.com. The spam gateway will forward mails to Exchange.

THe email address is xxx-xxxx.com. I guess it is not related to DNS naming or MX as only a particular sender can send through occasionally.

Ok, so you need to speak to your anti-spam people. More than likely it's rejecting the emails (maybe that address hasn't been registered correctly)?

It may be worth changing the MX to point to your Exchange directly temporarily, just to rule it out.

For Exchange Online Protection, I only need to enroll, change my MX record point to Exchange Online Protection server. Within the Exchange Online, I then point it back to my Exchange server, correct ?

Thx

Basically, yes. Although you should get a confirmed connection between Exchange and Exchange Online first.
