Your MX records are somewhat unique. While you may share MX records with a wealth of other customers, not every customer has the same MX records. When you sign up, you receive an e-mail with this subject:
New Email Hosting Account Information
You need to reference this to find your MX records.
This is example of what the e-mail might contain for the MX records:
DNS MX RECORDS:
mail.cloud3001.com (Priority 10)
mail-relay.cloud3001.com (priority 20)
(These above are both record type “MX” and should have the name value set to either @ or blank, not a subdomain)
Your SPF record is not as unique as your MX records. Your SPF record is a TXT DNS record at the root domain.
"v=spf1 include:_s00002163.autospf.email -all"
Your DKIM key is unique per domain. You can obtain your public DKIM key in DirectAdmin under “DKIM Keys” (look in the menus on the left side). You can find a tutorial for making use of it here: https://www.favehosting.com/knowledgebase/6/Set-up-DKIM.html
