When Fluid Topics sends an email on behalf of the mail server, the recipient's mail server can potentially identify the email as spam. To prevent this from happening, add one of the following to the domain's Sender Policy Framework (SPF) TXT record in the DNS (starting with v=spf1):
-
mx:antidot.net -
include:fluitopics.net
- When an SPF record is available, the recipient's mail server considers that a secure and verified entity sent the email.
- It is necessary to wait at least 24 hours for the new DNS configuration to apply.
