I am basically sold. I still want to learn how to set up my own server. I think it would be valuable to have an intranet accessed by VPN for REAL PRIVATE STUFF.
Any suggestions for uses cases with masked email? I think I get the concept and have ideas of how to make use of it, but maybe I am missing some scenarios. Like, can I have a prepared list of address to give out to strangers? Some times it is necessary, but I don't want some rando to take advantage of my trust.
