How to change forgot password email

We want to customise the forgot password email.

I searched all the static files greping the words in email and I wasn’t able to find where this email is constructed. I see in

/static/plugins/core.mailer/manifest.xml

that there is a subject, link etc. but there is no UI to change these or a specific template in code to edit. For example want to write "Sincerely, " instead of “Sincerely, Pydio”

Another question is how we can show the sender as

CompanyName < no-reply@company.com >. I tried this with mailer UI the Default From settings but it breaks the email sending.

Suggestions?

A I understand somehow we should override these: https://github.com/pydio/cells/blob/master/broker/mailer/lang/box/en-us.all.json
