Please have a read of my article so that you can identify which of your accounts the spammer is abusing so that you can stop this happening again, which it will:

You can use aquadmcli.exe to purge the queues quickly:

make sure your Exchange Server is not an Open Relay.

Optimizing Cloud Backup for Low Bandwidth

With cloud storage prices going down a growing number of SMBs start to use it for backup storage. Unfortunately, business data volume rarely fits the average Internet speed. This article provides an overview of main Internet speed challenges and reveals backup best practices.

Have you read my article?

You are either an authenticated relay and need to identify the account, or you are not recipient filtering and need to.

Which is it?

Who is the sender of the emails in your queue?  Random users from a domain not hosted by your server or postmaster@yourdomain.com?

yes alanhardisty, i read your article, and i thought it was very good. but maybe i didn't read something carefully enough.
all i know is that once i put postmaster@mydomain.com in recipient filtering, and checked  - filter recipients who are not in the directory, the attack stopped and my queue is perfect.
i can send and receive emails.
so should i keep postmaster@mydomain.com in recipient filtering? or are there problems keeping this setting?
now that my queue is clear, i don't have one of the bogus emails to look at who the sender was.
i did look at those emails when i had them, but i guess i couldn't tell who was the sender.

Okay - so you enabled Recipient Filtering - which means you now won't be sending NDR (Non Delivery Reports) back to spammers.

When you don't recipient filter, and you get inundated with spam, your server will accept all the messages, then try to deliver them, discover that the recipient doesn't exist and will then send a Non Delivery Report back to the sender, which will usually be a forged address, so a proportion of the NDR messages won't be deliverable (because they have been made up).

The problem is, that some messages will be sent to people that didn't send you messages and this will mean you will probably be Blacklisted on Backscatterer.org as a result.

Now that you have Recipient Filtering enabled, your server checks the Recipient details on inbound messages and if the Recipient doesn't exist on your server, the server will reject the message and the Sender will then be the one responsible for sending the NDR message (not you).

So - what was happening was that you were being inundated with spam and you were not Recipient Filtering.

You should now remove the postmaster@mydomain.com filter but leave Recipient Filtering Enabled.

Check on www.mxtoolbox.com/blacklists.aspx and see if your IP Address is blacklisted with Backscatterer.org.  It probably will be but will drop off in about 30 days time automatically.

Until then, you may have some problems sending mail to some domains because they will use this blacklist to reject spam and because they will find you on it, your messages will be rejected.

To bypass this, you can setup a new SMTP Connector to send emails for the problem domains via your ISP's mail server (Smarthost).

For details of how to do this, please have a read of the following:

ok, i took postmaster out of recepient filtering and all is still well with my queue.
also, i tried the link to see if i'm black listed, and i am not!! so good news, i guess i caught it in time.
any suggestions on how to clean up after this? i apologize in advance if the clean up is in your article, i started googleing so many things, i lost track of what was where.
my queue is nice and clean, i just didn't know if there were other things to consider.

Nothing to cleanup by the sounds of it.  If you have nipped the issue in the bud, then you should be fine.  Not being Blacklisted is good news.  Hopefully it will stay that way.

Recipient Filtering was the answer in this case, which hopefully my article would have pointed you towards as the solution.
