I've been using fastmail for a few years now and their reliability has been great, prices reasonable, and their web client is fast and convenient. But there is one thing I cannot figure out. I have my own domain, say me@mydomain.com. The host for mydomain.com really is just a mail reflection service which sends to me@fastmail.com. When I send an email from the fastmail web interface, my identity is me@fastmail.com, a…
Honest question: Why set up a mail reflection service rather than point your MX records at fastmail and actually use me@mydomain.com?
me@mydomain.com mywife@mydomain.com mychild@mydomain.com
Each redirects to a different real email account. The idea is that everyone knows us by our mydomain.com address, but reality we can change different mail accounts. Eg, my daughter has one with her university, but in a couple years after graduation, she can use a gmail account but all of the people using mychild@mydomain.com will never know she switched.
As I understand it, if I change my mx record, all of them will go to fastmail, but really I want only me@mydomain.com to go to fastmail.
