Hi there,
I’m looking for a technical contact who can answer some questions about the forthcoming deprecation of Basic Auth for NHS Mail SMTP. One of the software products we produce sends mail using a variety of NHS mail accounts, which are configurable by each trust. Some trusts have configured our software to send mail via smtp.office365.comwhich will shortly be migrated to use OAuth2 for authentication, however my question is really about some other mail hosts in use. For example, the High Volume endpoint at send.nhs.net or the national mail relay at relay.nhs.uk. Am I correct in thinking that these will remain on Basic Authentication for now?
Additionally, some trusts use internal mail relays with *.nhs.uk names. It’s not clear whether the authentication options for these will change.
Is there someone I can pick these questions up with please? We have previously raised with the NHS Help Desk, but they’re not equipped to answer this.
Thanks in advance,
Paul
