The primary domain for your organization is automatically authorized. If you want to create campaigns with other domains, before you can begin creating campaigns, you must authorize each of your additional domains. You perform this authorization by adding an innocuous text record to your domain in order to prove to the Barracuda PhishLine system that you own the domain. This is a security measure to ensure that you, in fact, have the authority to send emails to the domains you specify. The domain list is generated automatically based on the domains associated with each of the users you uploaded to your Address Books. You can also add the domains manually to authorize them in advance.
To authorize your domains:
- Navigate to Campaigns > Domain Authorization.
- Click New.
- Enter the Domain Name you want to authorize.
- Click Save.
- When the page refreshes, locate and copy the TXT Record Content for the domain.
- Add this TXT record to your domain through your DNS (Domain Name Server) provider, using the format
BLP=XXXXXXX. You can obtain instructions on how to add a TXT record to your domain from your DNS provider.
See important information about timing below.
Organizational email address books often contain emails from associated entities, like consultants, contractors, and partners. These entities should not be receiving campaign emails, unless you are authorized to do so.
Timing of Domain Authorization
It is best to perform the complete domain authorization process described above at one time, adding the TXT record to your domain soon after you add the domain to Barracuda PhishLine. The sooner you add the TXT record to your domain, the sooner Barracuda PhishLine will authorize your domain.
Barracuda PhishLine checks new domains for TXT records on scheduled intervals, as shown in this table:
|Time Since Domain Added||How Often Domain is Checked|
|< 24 hours ago||every 15 minutes|
|24-48 hours ago||every 30 minutes|
|40-96 hours ago||every 60 minutes|
|>96 hours ago||every 4 hours|
Campaign Schedules and Test Emails
You cannot schedule unauthorized email addresses in any campaigns. If a user attempts to send a test email to an unauthorized domain, the email will not be sent until you authorize the domain.
Identifying Unauthorized Domains
Unauthorized domains are listed under Campaign > Domain Authorization. You can filter by Validated to list only the unauthorized domains. In addition, Barracuda Phishline warns you in the following locations:
- Dashboard: If there are any unauthorized email addresses in any of your Address Books.
- Address Book: If there are any unauthorized email addresses.
- Campaign: If there are any unauthorized email addresses in the Address Books associated with the campaign.
