Hi Vicente,
It is up to the receiving mail server to accept or refuse (SMTP
error 550) a message from your domain. If you want to test your SPF
record, you can end it using ~all, for example:
v=spf1 ... ~all
To tell the world to refuse all mail that comes from a server NOT in
your SPF record, use:
v=spf1 ... -all
Does that help?
