Cause

Incorrect configuration of SPF records. Space or tabulation is present in the IP address filed of SPF record.

Resolution

1. Access Plesk database.

2. Get the list of all domains having an IP address in SPF record:

   # plesk db “select host,val from dns_recs where type=’TXT’ and val like ‘v=spf1%ip%'”

3. Review the IP addresses from the list for space or tabulation.

4. Log in to Plesk.

5. Adjust incorrect records for the affected domains from Domains > example.com > DNS Settings.
