Transitioning to PM (and generally speaking, to Proton For Everything) from Gmail, I was following the manual when I realised that PM wanted to replace my privately-owned, with mailbox service included, mail address.
What I’ve been doing for 15 years was hide a gmail adress behind my own domain name (quality of apps, quantity of storage, general user friendliness…); people would still see me as me@me.me, but I had the convenience of that google service while writing"as" me@me.
It also offered me a layer of safety, since downtime does happen, and hopping to the poor roundcube webmail interface of my hosting company allowed me to keep business as usual. Believe it or not, google has failed more often than that regional service provider. lol.
Now to the question: Am I right to understand PM will dutifully catch all emails to me@me.me, the DNS settings will kill my old-school IMAP mailbox to push them towards me@proton.me, and I will have to commit to trust Proton 99.95% (their current SLA for customers like me)?
Will I loose that last line of defense, Roundcube Webmail straight from my private provider?
Thanks is advance. For obvious reasons, I’m not on twitter, reddit & all that.
Sorry, not a native speaker
My domain name provider offers basic webmail service with my domain name
Gmail allows login in that service, writing "as* me@mydomain and retrieving incoming messages as well.
I’ve been doing this since 2006. If gmail is down, I just go to the webmail page for my domain and I’m good.
Your phrasing of “after the DNS update” made it clear for me: all mails are handled by the new service referenced by the new custom DNS entries. My mailbox attached to my domain doesn’t disappear, it is just not in use anymore.
Ergo, I loose the ability to log in to my original @mydomain webmail interface in case of proton outage/issue/billing conflict whatever. Or if money is tight.
