What is Spoofing?
Spoofing can mean many different things, but in the context of email, spoofing is a technique commonly used by spammers to hide the origin of their emails. When an email is delivered, it appears to be from one email address, when the email actually is from another address.
Think a letter you received in the mail with a return address that was forged to appear to come from someplace else. A common reason that spammers spoof your email is to attempt to trick the recipient into making a damaging statement or releasing sensitive information, such as passwords.
How do I know if I have been spoofed?
There are a few ways to tell if you have been spoofed:
- 1. Reports from users that received an email from your email address that seemed suspicious.
- 2. Bounce-back notifications from email addresses that you never sent an email.
How can I prevent my email address from being spoofed?
There are many ways to help prevent spoofing. Most of these methods are very complicated and technical. Unfortunately, none are fool proof. However, Network Solutions does provide a great method to help prevent spoofing that can be very effective.
This method involves adding a DNS record to your domain, called a Sender Policy Framework (SPF) record, to allow receiving servers to check whether the mail originated from you. This method is dependent on the receiving servers actually verifying this information.
Not all servers do this level of authentication, but this level of security is rapidly increasing. To do this, add the following TXT record to your advanced DNS settings within your Network Solutions account:
- v=spf1 include:spf.netsolmail.net -all
How do I re-point my domain to the My Advanced DNS Manager within my Network Solutions account?
Advanced DNS records are already configured to use your Network Solutions services. Advanced users may wish to modify these records to do the following:
- Add new hosts to the domain
- Change IP addresses.
- Modify where email messages are delivered.
This option is helpful if you want to keep one of your Network Solutions services active, for example, your email box, and host your other service, such as your website, with another provider.
To use the Advanced DNS Manager, your domain's nameservers must be moved to Network Solutions-managed nameservers.
Note: When you move nameservers to Network Solutions, your existing nameservers will no longer be used. As a result, website and email from other providers will be lost.
- 1. In the Account Manager, click My Domain Names.
- 2. Select the domain name you want to edit, then click Manage.
- 3. In the green box, select Change Where Domain Points.
- 4. Click Advanced DNS.
- You have re-pointed your domain.
How do I add this text record to My Advanced DNS Manager within my Network Solutions account?
Text (TXT) records have several functions. One common function is to use the TXT record to create a Sender Policy Framework (SPF) record. SPF records stop email spammers from forging the From fields in an email, which allows the owner of a domain to designate the IP address that can be used to send email from that domain.
- 1. In the Text (TXT Records) section, click the Edit TXT Records button.
- 2. Type a new Host name or 3rd-Level name under the Host field.
- 3. On the right-hand side of the page, insert your text record in the text box.
- 4. Then click the Continue button.
- A confirmation page appears that verifies your records have been updated.
- 5. Review the information carefully, then click the Save Changes button.
- You have updated your DNS records.
