Text-only format for outbound SMTP messages

[Georgi-K]

Context:
-> We are trying to implement a PGP-encrypted mail flow where Chatwoot is playing the role of the outbound SMTP client.
-> The latter is sending HTML formatted message to our Exchange Server which then is attempting to send to a PGP universal server.

Problem:
-> Chatwoot is sending HTML only formatted messages.
-> PGP universal is expecting Text-only format

As per this part https://github.com/chatwoot/chatwoot/blob/develop/app/mailers/application_mailer.rb , we are seeing that the format is always HTML:

def send_mail_with_liquid(*args) mail(*args) do |format| # explored sending a multipart email containing both text type and html # parsing the html with nokogiri will remove the links as well # might also remove tags like b,li etc. so lets rethink about this later # format.text { Nokogiri::HTML(render(layout: false)).text } format.html { render } end

Is there an option to send text-only messages ? If not, can you please consider that feature?
