I’m working on a Workflow that would send Tasks, not only to people within my organisation, but also to external people. In my tests to my private email address I have noticed that email@example.com gets marked as SPAM and also if I use a different address like “firstname.lastname@example.org”.
I thought if I would add an SPF-record to my domain’s DNS-records that it would decrease the chance that the email would get marked as SPAM, if I use “email@example.com”. But what would be the exact SPF-record to add? And are there any more settings like DKIM I could add?
