About a third of my domains are on Fastmail for family members to use and for emailing businesses that would spam-flag VPS CIDR blocks. I've taught family members to create aliases for email canaries so they can nullify companies that sell or leak their address. About a third just point to my name servers and accept email for my domains and most of the popular email domains to give spammers a feeling of accomplishment and to pre-populate ISP DNS caches. Those servers just dump the email into a single flat file. I use these for sending to known malicious entities or when I need a throw-away temporary email address. I just grep out what I need from the text file. The remainder of my domains just point to non-routable public addresses.
