I think I will make a feature request. As part of manage I can ‘invite’ a user who is LDAP enabled. This has an email icon for the ‘invite’ - So I feel like this should already be there.
To be maybe clearer, it does use email, it just doesn’t use direct SMTP. It assume that local sendmail delivery is configured the way you want it. You can use something like ssmtp if you just want to relay to a “real” mail server.
