Solid base — one policy step remains.
lincoln.ac.uk publishes an enforcing DMARC policy, so mail that forges its domain is quarantined or rejected at the recipient.
Your SPF check is close to the DNS lookup limit, which means email checks for your domain are getting too complex. This matters because if the limit is exceeded, some mail servers may stop trusting your messages or fail to validate them. The fix is to simplify the list of allowed mail senders, usually by removing unneeded services or flattening the setup so it uses fewer lookups.
