Does SPF not broke the forwarding of e-mails to other servers?

On all our servers, we have correctly configured SPF (Sender Policy Framework) records for the purpose of correctly receiving e-mails by other servers.

The servers also operate correctly forwarding mail, by the correctly configured SPF mechanism: SRS (Sender Rewriting Scheme). With this mechanisms you can safely send emails further, with the certainty that e-mails will reach recipients and will not be classified as spam.
