Is your feature request related to a problem? Please describe.
This feature request covers the usage of automated "+" aliases in mail responses. When receiving a mail on one of the aliases such as "username+alias[@]domain.tld", we can only respond using the main "domain.tld", "protonmail.com" or "pm.me" address which in some cases breaks ticketing software which relies among other on the sender address.
Describe the solution you'd like
When changing the sender address in a response to a mail sent to an alias (by pressing the "From" field), the ProtonMail app should also propose the recipient alias as a valid sender address.
Describe alternatives you've considered
One of the current alternatives is to use a desktop app where we can add new SMTP entries using the alias as username.
Additional context
Beneath a screenshot of the available sender addresses where one would expect the recipient alias to be listed.
