Your DuoCircle account has been created, and you're all ready to go!
Let's turn on your DuoCircle service.
There are 2 steps needed to turn on the DuoCircle service for your domain. All you need to do is set your destination server and change the DNS MX records for your domain. (If you don't know what this is, or you don't know how to change these records, talk to your, domain registrar, hosting provider or ISP, and they'll be help you to make this change)
Set a destination server:
Destination servers are where we send your mail once it's been accepted, filtered and scanned by our mail system.
This is the port our mail system should use to communicate with your destination servers.
It can be in the format of a Host Name or IP address
Make sure that you can receive mail on these ports...
The Email Gateway service supports relay to any of the following ports: 24, 25, 26, 587, 2525, 10025, 52525

Your MX records probably look like this:
MX 1 mail.yourdomain.com. MX 2 mail2.yourdomain.com. OR MX 100 mail.yourdomain.com.
Okay, let's change your MX records.
Take care! Incorrect MX records will cause incoming e-mail messages to bounce, or worse completely disappear. If you aren't comfortable making this change, please talk to your hosting provider.
You need to change your MX records to look like the following:
MX 10 mx1.mailhop.org. or your custom MX record MX 20 mx1.mailhop.co. MX 30 mx1.mailhop.co.uk MX 40 mx1.mailhop.us
It's important that the numbers — the MX priority — are exactly like the above. Remove all other MX records, so that the only MX records are the ones pointing at DuoCircle.
You're all done!
The moment you save the change to your DNS, e-mail messages from domains that don't have your DNS cached will start flowing through the DuoCircle servers. This means that you'll start seeing less spam pretty much immediately, and within about two days all of your domain's incoming e-mail should be going through the DuoCircle filters.
After a few days to let your DNS change propagate to the entire Internet, advanced users can make a change to your e-mail server configuration, to only allow e-mails entering from the DuoCircle servers. This will eliminate "transient spam", where spammers will ignore the MX records for a domain entirely and instead simply connect to every possible IP address in your network, trying to send spam to your domain.
