I followed tons of online tutorials, guides and even the post here about setting up SPF records in Plesk 11.

I'm using plesk 12 on Ubuntu 12. I have set the following:

*.webmail.gecab.nl. CNAME   gecab.nl. / 24  PTR gecab.nl.
_domainkey.gecab.nl.    TXT o=-
default._domainkey.gecab.nl.    TXT p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDKzW2VeEOVrpxoAw8VSW+W6tmylhdJDCiIbBu24B9/+qbkvK6VZl3dO5GvrsMiarM40fxMVlAtr47ccBWOy53KsKK+ACfxiN3FB0VIsrbKM2OtBQul6Q9GHN9FfojhHauCWOKIJBV/H5DYfeYAQPDZHbfcYOVbUKnR3rDvYHbnjwIDAQAB;
dev.gecab.nl.   A
ftp.gecab.nl.   CNAME   gecab.nl.
gecab.nl.   NS  ns.gecab.nl.
gecab.nl.   A
gecab.nl.   MX (10) mail.gecab.nl.
gecab.nl.   TXT v=spf1 ip4: -all
ipv4.gecab.nl.  A
mail._domainkey.gecab.nl.   TXT v=DKIM1; k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDC2wGgC7itM7IRnrYG6EbfY9OxZwqlGUfChLprKfCZaVBY6R9MSvTn+4RrftOlWDjDhDfC0IuuRmLuZm7KifZE7+qA2s9i1varZqTXVtITksLNSy39Bhb9IHj74UwPKRhT7bGMbKYVr5ScQ1LYbw1zRHqfyzeBDtkqZfkzKFpU8QIDAQAB
mail.gecab.nl.  A
ns.gecab.nl.    A
webmail.gecab.nl.   A
www.gecab.nl.   CNAME   gecab.nl.

I have also tried:

v=spf1 ip4: ?all
v=spf1 ip4: +mx +a -all
v=spf1 ip4: +mx +a ?all

I also got errors with the Domainkey record and DKIM. Both saying key can not be found. (changes are made more than 48 hours ago).

  • Are these from an actual zone file on copied from Plesk's web based UI? In the zone file, contents of TXT records should be inside quotation marks. Mar 12, 2015 at 13:37

You've probably set your DNS records in Plesk, This won't work because your DNS is set to ns.stratoserver.net. Login to your account @ strato and set your records there. You can copy the SPF and DKIM records from Plesk to the Strato DNS.
