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.
MicrosoftExchange329e71ec8 8ae4615bbc 36ab6ce411 09e@domain .com keeps sending emails to bma_journal@bma.int. 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 MicrosoftExchange329e71ec8 8ae4615bbc 36ab6ce411 09e@mydoma in.local to the @bma.int 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.
Thanks

First step I would take to remove anonymous setting relay connectors. Then you can work on virus clean up.
MicrosoftExchange329e71ec8 8ae4615bbc 36ab6ce411 09e@domain .com is a microsoft default MicrosoftExchangeRecipient EmailAddre sses and is used by a misconfigured system. No malware.

Amit: I am unsure how to do this.
Neilsr: If the MicrosoftExchangeRecipient EmailAddre sses is MicrosoftExchange329e71ec8 8ae4615bbc 36ab6ce411 09e@domain .com that means that the system is misconfigured?
MicrosoftExchangeRecipient EmailAddre ssPolicyEn abled is set to true. (attched results from Get-OrganizationConfig)
Thanks for the responses

bma_journal@bma.int
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.

We used to have the archiver in place but don't anymore. Which is why it's confusing. There is also no bma_journal@bma.int on our exchange server or no journaling rules.
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.

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.
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.

I'll go through in the morning and check every setting listed. Thanks for the link man.

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.

You are the freaking man!! It was stuck in the queue on resend. Makes perfect sense! I just removed it and the problem went away.
Awesome!
