Email "no-reply" address

Hi Five Team,

In my application, users send emails (Mail Merges) using my own SMTP server. I configure the context in a JavaScript function like this:

const messageContext = {};
messageContext.SMTPSubject = courrielData.smtpSubject;
messageContext.SMTPFromName = currentConfig.senderName;
messageContext.SMTPAddresses = currentConfig.to;
// … cc and bcc …
I would like to add a “Reply-To” header so that when a recipient replies, the response goes to the user’s personal email instead of my system’s “no-reply” address.

Example of what I want to achieve:

Is there a reserved property in messageContext for this (e.g., SMTPReplyTo)?

Thanks!

Jean
