I have many email addresses: several going to the same mailboxes and I even have a couple of catch-all domains: domains that will accept ANY recipient email and simply drop them in the same mailbox.
When I answer an email that was sent to one of these aliases or to a catch-all domain, I would like the sender’s email to be the “correct” one: the one that was used as recipient in the original mail.
I cannot see how to do that in EM client: I can chose the source email in the dropdown but I can’t chose the original recipient or use whatever I want (free text).
For those wondering, I’m doing that because I’m tailoring the email I provide to companies and web contact: on each web form I need to register on, I use something like “email@example.com” (where “domainname” is the name of the domain where the web form I’m filling resides). It allows me to blacklist a lot of spam, limit the scope of data breach, reduce the amount of cross-referencing that can be done using my email, etc.
