The OP complained that Xtra were rejecting forwarded email due to SPF, which is fair enough, as his server was not in the SPF list of the sender's domain.

The issue seems more that large providers have platforms that classify/learn/profile your servers (e.g. Cisco).

So if you are forwarding Spam to Xtra (via a redirected mailbox) your server may end up greylisted or worse still globally blacklisted by global users of the large provider's platform.

This is not really an SPF "issue".

Or rather, are not broken by SPF. Unfortunately, the same is not true
of DMARC. There's still no good solution for lists or forwarders that
are broken by DMARC. Glen, I fear that DMARC problems are in your
future.
