How To Add a New Domain into a Sonicwall Email Security Appliance (Inbound)


You have purchased a new Email domain which you would like to receive mail on. You have an existing Sonicwall Email Security Appliance (ESA) in place and you need to configure it to accept the new email domain.


Log into your Sonicwall ESA via the web interface and log in as the ‘admin’ user account. The default username and password for this account is admin/password. Hopefully you will have changed this. If you haven’t, you need to…

Once logged in, carry out the following to get you to the right place:

Expand System>
Expand Network Architecture>
Click on Server Configuration>

In Server Configuration – All in One>
Highlight the inbound Email Flow Path and click ‘Edit Path’>

Add new domain into the list.
Scroll down to the bottom and click Apply

Side note:

Remember to configure your Email Server to receive on the new email as well.

Changing the Default SBS Mailbox Database

Changing the Default SBS Mailbox Database

Sometimes it is more practical to create a new Mailbox Database and move the mailboxes opposed to moving the Database via the SBS Wizard. The problem is, when you’ve done this and deleted the original Database it stops the SBS Console from creating any new mailboxes when creating a user, this is due to it trying to create the mailbox on the old (now removed) mailbox database.

The warnings received in the SBS Console are:
‘Unable to find the default mailbox database. Make sure mailboxes database exists and you have access to view the database’
‘Mailbox does not exist for reciepient of welcome mail.’

How to update the default mailbox database:
– Open the Exchange Powershell as Administrator
– Run the following command to get the mailbox Database name:

The outcome will look a little something like this:Get-MailboxDatabase

– Open the registry (regedit) and browse to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SmallBusinessServer\Messaging

– Update the String value of MailboxDatabaseName to the name of the new mailbox database name
