You could use haven relay with integrated blossom server.
Discussion
Or just read the blossom-server github page
Yep. But there is no tutorial in that repo.
He wanted a tutorial and the haven readme describes every step of the installation.
That relay looks interesting but its only antispam features is the retarded web of trust? Better off with strfry
If I would setup another public relay I would go with strfry too.
But for a private one haven is great. Especially the blast feature which broadcasts note to plenty relays.
Sounds a bit complicated for me personally, but thank you
