Actually, I don’t see how to use the list: it’s subject to change, and unfortunately doesn’t include contacts. 

More useful to know is that next level subdomains of .sch.uk can only be registered by local education authorities, which are branches of local government in the UK. And each subdomain of a subdomain of .sch.uk can only be registered by a school. So, it’s unlikely that subdomains of .sch.uk will be registered maliciously. 

Similarly, .ac.uk is reserved for higher education institutions in the UK. So they’re unlikely to be registered maliciously. 

So, an SPF pass, or valid DKIM signature in such a domain is likely to be coming from a legitimate source. 

However, account compromise is not uncommon: partly because the domains are quite attractive to spammers. So, don’t adjust your spam score, but do adjust your strategy when discovering spam. Reports of spam from .ac.uk or .sch.uk accounts are likely to be taken seriously, and contacts should be relatively easy to discover.
