Hi Trever/Kai,

The tokenization changes were added to support multiple strings in txt
record. If you want to use a single string with spaces in it as a txt
record, you have to quote it twice.

  samba-tool dns add s4server example.org example.org TXT "'v=spf1 mx -all'"

If you are using nsupdate to add the record, then make sure to quote
it as follows:

  server s4server
  update add example.org 3600 IN TXT "v=spf1 mx -all"

That should get you the desired result.
