We publish an SPF record which you can use if your outgoing mail is sent via
our mailhubs, at
You should use the
include mechanism to reference this record from
your own SPF record. Normally your SPF record will need to go at the root of
your domain, which is named as
@ in the DNS. So your overall SPF
record might look like this:
@ TXT "v=spf1 include:_spf.mythic-beasts.com -all"
Beware that with this record in place, receiving servers are expected to reject mail that purports to come from your domain but is not sent by our mailhubs. You should be sure that this is the case before using this SPF record. Two particular things to think about are websites that may legitimately send mail using your domain name, and redirections.
Note that this record ends with
-all, which indicates a
fail. If you are publishing an SPF record for the first time, you might
prefer to replace
~all which is the less
drastic softfail. Unfortunately it can be hard to evaluate the impact of
SPF records, since their effect takes place at the receiving end.
Note that you should use a
TXT record. There was once an
SPF record type, but (for complicated and controversial reasons)
this is now deprecated, and is no longer supported by our control panel.
