Two ideas:
xmpp works, but the domain needs to resolve correctly. I'd just use a free domain that you point at the server LAN ip, plus an acme client that can do a dns challenge. Prosody is pretty bulletproof and very lightweight.
deltachat + email. Set up a little IMAP server for the lan and use Delta chat to create a messaging over it. Or just use an email client.
