First, verify that your outgoing server configuration in Evolution is
correct, ie. you are using the proper settings according to the instructions
you should have received from your email provider.

Do you know what SPF is? If not, you should google and read a bit about it.
Basically, it is a way for domain owner to restrict which servers can send
mail on behalf of that domain. Let's say the example.com domain defines a
SPF record that says only mailout.example.com can send mail for this domain.
In that case, if you use an @example.com address and try to send mail from a
different machine than mailout.example.com, the receiving server may (if it
does the SPF check - it is up to the receiving server configuration) reject
your mail with a message like the one you quoted.

You must use the proper outgoing SMTP server as instructed by your provider
and you must *submit* the mail to that server via authenticated submission
(on port 465 or 587), not just send it to port 25.

If your Evolution is configured properly and it worked previously, but
recently stopped working, it is possible that your email provider has messed
something up with their SPF settings. For example, they moved the server to
a different IP address and forgot to update the SPF record. In that case you
should complain to your provider and make them fix things.
