The following changes have been rolled out to production:

  • When you use FastMail's nameservers for your DNS, one of the default
    records we publish is an SPF
    record. Until now, we've published this as a TXT DNS record type
    and a SPF DNS record type type.
  • SPF DNS record types have been deprecated
    ( for a while, so
    we've now removed the SPF DNS record type and are only publishing
    TXT DNS records types.
  • This shouldn't affect anyone, but we've put up this post as
    informational for anyone experiencing some
    issue with ancient software or systems.
