ExchangeDefender Security Compliance
ExchangeDefender is helping our clients and partners comply with email validation & authorization requirements. DMARC (SPF + DKIM) help prevent unauthorized hijacking/spoofing of your domain name and are used by email services to separate legitimate email from SPAM.
We’ll offer assistance for SPF + DKIM
In order to assure reliable email delivery, ExchangeDefender is offering assistance with SPF + DKIM rollout from September 20th through October 20th. All domains must be brought to compliance by October 30th, 2021 in order to continue relaying mail through ExchangeDefender. We’ll even do it for you, for free.
For more information on our new email security standards, please see our DMARC webinar, and read our DMARC guide.
Every domain that uses ExchangeDefender to send or receive email is required to update their SPF and DKIM records. Failure to comply will result in having your email bounced.
How to get started:
Step 1: Contact your DNS Administrator
You will need to contact your DNS administrator or DNS hosting provider to create the following DNS records:
SPF Record
DNS Record Type: TXT
DNS Record Value: “v=spf1 include:proxy.exchangedefender.com -all”DKIM Record
DNS Record Type: TXT
DNS Record Hostname: default._domainkey
DNS Record Value: “v=DKIM1; k=rsa; s=email; p=MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAwkMvl3dS3g9XbhxtD16tSx/l+s0cxVv73/NCHywH2HFED61k+orBj4QY96FJcUD7MOwmwjC7Igtz5P9fVOLFoMr+d8g8c5J5OIA8Xj2ap4jsEnSF3rRrCNJDxojPvtGA1+ENwGpheHtniZG/fgVguDL+M1zXNRsYTybzKwU49tmP4RyIFIC8NEV7jqrGSVWpQSXc12JlvmLQX1J5tdnWvTR7/NGOzyth0rYP1STKj1hHU9ZVN+x8VFiumlPdpDQBMn5Bzu/Cs6pzrSHJqGBcVer4mccpnCOX9bG3sR7wU6nDIv3rvwIlfBymylcZruJvjsXZAZaameUBpgGgmibpkwIDAQAB”
Step 2: Validate your DNS records
After the DNS records are published please validate them using public tools like MX Toolbox (https://mxtoolbox.com/SuperTool.aspx) or DMARC Analyzer (https://www.dmarcanalyzer.com/dkim/dkim-checker/). Until your DNS records validate, you are not in compliance and will have issues with email delivery.
Step 3: Turn on DKIM signing
After your DNS records have been published and validated, you will need to turn on DKIM signing. Go to https://admin.exchangedefender.com, login as Domain Administrator and go to Mail Flow -> DKIM Signature.
Finally, click on Accounts and confirm that all your email addresses are listed and associated with appropriate users.
