libsrs2: libsrs2 (Sender Rewriting Scheme library)
libsrs2:
libsrs2: libsrs2 is the next generation SRS library from the original
libsrs2: designer of SRS. It implements the Sender Rewriting Scheme, a part of
libsrs2: the SPF/SRS protocol pair.
libsrs2:
libsrs2: SPF (and related systems) present a challenge to forwarders, since
libsrs2: the envelope sender address might be seen by the destination as a
libsrs2: forgery by the forwarding host. Forwarding services must rewrite the
libsrs2: envelope sender address, while encapsulating the original sender and
libsrs2: preventing relay attacks by spammers.
