Configuring Domain Settings

(Bolded fields are required)

Domain Information

Domain name The domain to be added to the service
Transport The server to which filtered emails will be sent
(can either be a hostname like "mail.example.com" or an IP address)
Transport port SMTP port to be used when sending you filtered email (default: 25)
Domain Type Whether this is a standard or a mirror (alias) domain.
Declared nb of mailboxes
The number of users on this domain. This information will be used for billing on Standard domains.
Test email
A valid email address on the domain. This will be used by Cumulus to test that it can successfully deliver mail to the server set in the Transport field.

Description

Additional note you can use to store info about your domain (i.e. what it's for)

Transport hold Explicitly set our servers to hold the delivery of emails. (for a maximum of 5 days)
Use the hostname's MX record Allows delivery of emails to the MX records of the hostname in the transport field (used to delivery to multiple servers)

Recipient Information

Nb mbx used Indicates the number of email addresses to which at least one message has been delivered
Rejected recipients count Indicates the number of recipients whose email passed through the filter but were rejected by the next server in the delivery chain
Count start date Date when the count began

Adding a Domain

If your service was purchased through a distributor portal, you will be unable to add domains directly in Cumulus. Additional domains must be added through your distributor portal.

1

Click the Add a domain link near the top right of the domain table.

2

Fill in basic information and set any options you may want as explained in Configuring Domain Settings

Once the domain has been added, our API will automatically test whether we can successfully deliver an email to the test address you specified. If we detect a problem, you will be automatically notified so that you can make the necessary corrections.

If no problems are detected, you will receive instructions containing your MX records and firewalling information once your new domain's configuration has been propagated to all our filters. This can take up to 5 minutes after the domain has been added.

It is important you wait to receive our MX change instruction email before modifying your MX records. This email is only sent once all backend configuration has completed. Changing MX records before receiving this email could result in loss of emails.

Removing a domain

1

Click the Delete link near the top right of the domain table.

2

Use the checkboxes to choose which domains you wish to remove and click the Delete button when you are done.

Please note that a domain cannot be removed as long as it's MX records still point to our service

Changing the Transport

1

Click the View link for the domain you wish to modify.

2
In the Domain Information section, click the Edit link.
3
Edit the Transport field and click the Save button.

Changing the transport will trigger an automatic SMTP test. Our filters will send a test message to the server  [Transport] on port [Port] to the address [Test email]. If this test fails, your relevant Contact Persons will be notified.

Standard vs. Mirror Domains

For billing purposes, we only want to take into account each user and each final destination mailbox once. If you use two domains for email and one of your users has one or more addresses on each domain, it should count as only one mailbox. To help make the distinction between domains which include billable mailboxes and those that are only made up of aliases towards mailboxes which have already been declared, Cumulus allows the creation of two domain types: Standard Domains and Mirror Domains:

Standard Domains

Standard domains are any domains which include mailboxes which haven't already been declared under another domain. The declared number of mailboxes will be counted towards the total number billable to your account.

Mirror Domains

Mirror domains are domains which only include mailboxes which have already been declared under another domain. The declared number of mailboxes will not be considered in your total billable account. 

If a domain involves both aliases and unbilled users, it must be considered as a standard domain and the number of distinct users declared for this domain.

Examples

Business A uses two domains: example.com and example.org. The domain used the most is example.com but all the users have email addresses on both domains. On example.org, all the addresses belong to users who have an @example.com address. In this case, example.com is the standard domain and example.org is a mirror domain. 

Business B uses two domains because it uses two different affiliates: mydomain.com and myotherdomain.com. In total, 175 people have a "mydomain.com" address and 50 people have a "myotherdomain.com" address. Out of these 50 people, there are 10 who have a "mydomain.com" address. In this case, both domains are standard domains and so there are 175 mailboxes under mydomain.com and 40 mailboxes under myotherdomain.com. 

Business C also uses two domains: maindomain.com and secondarydomain.com. All the users who have a "maindomain.com" address also have a "secondarydomain.com" address. However, on secondarydomain.com, there is a distinct user who does not have a "maindomain.com" address. In this case, secondarydomain.com is a standard domain for which a mailbox must be counted.
