Hey folks, I have my personal domain (ian.gay) on Cloudron and right now it's fully configured to send and receive email. I was looking at moving just my personal email to Protonmail for a few reasons but it seems difficult (if not impossible?) to split mail like this.
Would I need to receive everything on my cloudron first, then forward to proton, or is there a way to use a mail subdomain on Cloudron (like cmail.ian.gay having a different mx than ian.gay) ? Or is the only solution just to set it to send-only and use a different address for Cloudron? Has anyone tried something like this?
@ianhyzy Haven't tried it but sounds useful and also do-able.
I have the reverse : primary email on protonmail and would like a subdomain of primary to be in cloudron.
I think it's possible.
At least for because I use the wildcard DNS approach.
@ianhyzy yeah, it's not possible since email delivery works at a domain level and not mailbox level. The best you can do is to have email of some mailboxes forwarded from Cloudron to Protonmail or vice-versa. In the next release, we are trying to make email forwarding setup simpler, so maybe it will help in this situation.
It would be an interesting feature to have the mailserver for a domain be able to recognize that a mailbox it is receiving for is elsewhere and redirects the connection there.
This would be at a higher level than where forwarding happens.
Just like when one moves IRL and tells the Post Office the new address.
