New Exchange User cannot receive External Mail

Exchange 2003

New user account.

E-mail can be sent internally/externally and received internally. No external e-mails can be received.

E-mails from external sent to existing user and new user get to existing user but not new user. The e-mail is getting through the firewall and the gateway.

Any thoughts?

The only thing I can think of is the properties of the user account is not allowing external mail.

exchange general tab
delivery restriction button
under message restrictions select only the radio button "from everyone"

You should create a new test account and see if the problem persists.

Also, any undeliverable "NDR" messages getting back to the sender?

Could this be a licensing issue and if so, how can I tell?
Donnie4572IT Manager

Commented:
No.
Licensing CALS for both windows 2003 and exchange 2003 is on the honor system.

However you should verify you have enough licenses, in case you are audited by MS.

Did you check message tracking as pointed out by amaheshwari?
Do you have message tracking enabled?

I have 25 licenses for a staff of 21 so thought I'd be fine but just wanted to ask..

I've tried message tracking but only a limited number of messages are in there (ie. not everything I've sent/received is there). I'll review the link you sent tomorrow morning and post back here.
What protocol do you use to receive external email? POP3? If so have you created POP3 connector for your new users?

If you are using something else other than POP3, you may try to create a POP3 connector for one of the new user for testing purpose.

Turned on message logging and the found that the e-mail I'm sending frm external is getting through to the existing user but not to the the new test user. There is no record there for the new user.

- I'm not 100% sure. New to the Exchange/Mail Administration. How would I tell? Believe we're SMTP.
Can you remove that user account and recreate it? Who host your external mailbox? Do they have the usr account setup there?

Author

Commented:
Haven't removed it but did setup another test account and no luck, same symptoms, everything works except receiving e-mail from external sources. User account is through our own Active Directory.

mail enabled user...
can you check that they are getting email addresses assigned?
email address tab of the user properties.

Author

Commented:
Addresses are being assigned. SMTP and X400. Would I be correct in saying that it seems that the SMTP address is not working but the X400 is?
Silly question - have you checked your spelling in the email address?
Donnie4572IT Manager

Commented:
not a silly question...
how many reciptent policies do you have?

All internal mail has no problems...correct?
external mail to new users are not making it to your exchange...correct?
Do you see any mail in the queues?

Author

Commented:
Nothing silly now... yes, spelling is correct.

Author

Commented:
how many reciptent policies do you have?
- 2. One that ran 3 years ago (once). And a default policy that applies to all SMTP addresses.
All internal mail has no problems...correct?
- that's correct
external mail to new users are not making it to your exchange...correct?
- seems correct
Do you see any mail in the queues?
- what queues? An external mail sent to both existing user and new user gets to existing user but not new user.
Donnie4572IT Manager

Commented:
ESM
server name
queues

any messages in there waiting to be delivered to the new users?

if you check message tracking for the inbound mail adding the new user to the recipient field, do you see any tracking for incoming external mail? If no, send a test incoming message and check again...if it does not show up in tracking then it neaver touched your exchange. If this is the case then you must look upstream like gateway device firewall ect.

Nothing in the queues.

Like I said before, I've sent a test message to both new and old on same message and can see the message in the tracking for the old account but not the new.

Guess looking upstream now but can't imagine what would be filtering the message. Same domain, just username is different. It's not being filtered at the gateway, I've checked. The firewall... can't imagine why the same message from the same sender makes it to one and not another.

A solution has been found:

I found that if we by passed the mail gateway, mail works inbound. In going through the gateway, only new users were not receiving email. In troubleshooting the mail flow, I found that the LDAP from the mail gateway to active directory was broken. Connections were not transferring between the gateway and active directory so "new" users were not being recognized as being legitimate. Since SPAM protection compares against this AD list, and since it was not pulling current users, mail was being dropped as Phishing traffic.

So, I corrected the LDAP sync to the mail gateway.

Just thought I'd post this to close this issue. Phew........

Thanks for the update. I didn't think of LDAP at the gateway since I do not use this. Glad its working.
