Exchange sending continuous messages and it's caught in a loop

We are having problems with our client's exchange 2010 server on a 2008 r2. keeps sending emails to This seems to be caught in a loop of some sort. They are being stopped as outgoing mail at our Barracuda mail filter and are being sent at least every minute or so.
 They are being sent by MicrosoftExchange329e71ec88ae4615bbc36ab6ce41109e@mydomain.local to the address. Our mail filter is catching it but i suspect that there is some sort of malware on our exchange server.
I am running Trend Micro scanmail on our stores right now. It's found some malware but the issue is still here.

First step I would take to remove anonymous setting relay connectors. Then you can work on virus clean up.
Neil RussellTechnical Development LeadCommented: is a microsoft default MicrosoftExchangeRecipientEmailAddresses and is used by a misconfigured system. No malware.

See this article that explains.

Amit: I am unsure how to do this.

Neilsr: If the MicrosoftExchangeRecipientEmailAddresses is that means that the system is misconfigured?

MicrosoftExchangeRecipientEmailAddressPolicyEnabled is set to true. (attched results from Get-OrganizationConfig)

Thanks for the responses

Making Bulk Changes to Active Directory

Watch this video to see how easy it is to make mass changes to Active Directory from an external text file without using complicated scripts.

Sounds like you have a Barracuda Mail Archiver in place. Was anything changed with its configuration, or, did this loop occur after changing any settings in the send/receive connectors in Exchange?

I know the Barracuda Mail Archiver has you create a dedicated Send Connector during setup. See here for the documentation.
JoeSystems AdministratorAuthor Commented:
We used to have the archiver in place but don't anymore. Which is why it's confusing. There is also no on our exchange server or no journaling rules.
Gareth GudgerSolution ArchitectCommented:
Sounds like you still have some leftover Config then.

Not 100% sure if the Barracuda Mail Filter needs any of the items described in this setup guide though. Wouldn't think it would.
JoeSystems AdministratorAuthor Commented:
Yeah i've been looking for the config. I just can't find it. It's crazy. I'm digging through exchange and no luck. I'm gonna try a reboot too. It probably won't fix it but it can't hurt.
Gareth GudgerSolution ArchitectCommented:
You might be able to just reverse what that previous document I linked said. Just go back and remove the settings the document tells you to create.

Can't imagine it would affect the Mail Filtering product.
JoeSystems AdministratorAuthor Commented:
I'll go through in the morning and check every setting listed. Thanks for the link man.
JoeSystems AdministratorAuthor Commented:
I've gone through all these setting three times and still have found no remnants of the bma_journal address. Only on the mail filter.
Gareth GudgerSolution ArchitectCommented:
This may be why it is trying to send it externally. Because it doesn't exist internally anymore.

Are these messages getting stuck in the queue? Or is the Mail Filter just dropping them?

Sounds like this might be a call to Barracuda.
