SPF Records and Domain Keys: Combating SpamWritten by Brad Markle
Setting up a SPF record and domain keys are great ways to protect your email from being spoofed and receiving spam. Spoofing is a method in which someone sends email and it appears to come from your email account. However, it does not. Spam is unsolicited emails, also known as junk mail.
Domainkeys is an email authentication system that verifies all incoming mail has not been altered. This is done in a manner that the email message is coming from the correct sender and increases the ability to track spam and combat spoofing. For more information about Domainkeys please visit the Knowledge Base article here.
SPF records basically specify which servers are allowed to send email on behalf of your domain name. Default SPF settings will only allow email to come from your InMotion Hosting server. If you use another server for email, such as Gmail, you can authorize emails to be sent from those servers as well. For more information on SPF records please visit our knowledge base article.
