no. Only outgoing mail servers really need to be in SPF records.

for the incoming mail you need either to make sure your MX adds Received-SPF
headers properly (apparentlky they don't), or set
"ignore_received_spf_header 0" and set up trusted_networks and
internal_networks properly, so SA knows which header to use for SPF checks.
