Notes on Capabilities
DMARC: Our data indicates NoSpamProxy supports full DMARC compliance.
DKIM: Contact NoSpamProxy for DKIM setup.
SPF: There are two suggested includes - 'include:_spf.nospamproxy.com' and 'include:spf.servicemail24.de', however this most likely broadens the list of authorized servers beyond what you need. Before making changes to your SPF, be sure to contact NoSpamProxy and verify if there's a more customized list of servers they can provide.
