Thanks. Great ideas. Had not considered the web issue. I actually have a VPS for other things at Linode. I could just add my new “.net” domain to that and setup something. Let rest is fine. We are transitioning over the next 6 months and hope to not change for a long time after that. So we have time to get this correct.
I also have mail setup in my VPS for other reasons so I do understand mail basics. Including SPF etc. Never really had any delivery issues but I do not use it generally. I think my old domain which I have had for 5 years has a fine reputation. Good point about the one I just purchased. Just do not want to move my general mail there or commit to setting it up and worse maintaining the multiple VPS systems needed to really do mail correctly. That is, I would want to have at least two incoming SMTP servers in two different data centers then maybe separate IMAP server too that they route to. Then there is the webmail client and locking it all down. Cost and worse yet effort and time mount up and it’s not a one time deal. Not something my wife could do and not me 20 years from now.
