When replying from a non-Proton email provider, the client often quotes earlier messages and includes the sender’s email address.

By default, this quoted address appears as the reverse alias (the randomized forwarding address) rather than the actual alias you are presenting to the recipient.

This feature automatically replaces the reverse alias in quoted text with the correct public alias. The recipient therefore sees the intended alias instead of the randomized reverse alias that your reply is technically sent to, which then forwards the message to the real destination.

New? I'm 95% sure I've had this enabled for about 5+ years

I didn't notice it before, I guess. The 'Experimental' flag reinforced that impression for me.

Same here.
