Undelivered Mail Returned to Sender - Show Original

Postby blueflametuna » Mon Jan 07, 2019 9:24 pm

Running 8.8.7_GA_1964.FOSS - Bounced emails are being returned with the original message as an attachment. (javascript link).
Is there a simple configuration setting to have them returned in clear text instead?

The only thing I could find is this obscure reference in bounce:

bounce_size_limit (default: 50000)

The maximal amount of original message text that is sent in a non-delivery notification. Specify a byte count. A message is returned as either message/rfc822 (the complete original) or as text/rfc822-headers (the headers only).
With Postfix version 2.4 and earlier, a message is always returned as message/rfc822 and is truncated when it exceeds the size limit.

Does Postfix mail_version = 3.1.1 have a different default than message/rfc822?

Let me rephrase the question ...

Our customer is using a pop client, not the Zimbra client, and thus, not web based. (so never mind the javascript).

The mailer-daemon NDR bounce notifications being sent are including an .eml file attachment as the original email.
Is it possible to compose the mailer-daemon response message to include the original email in clear text rather than as an attachment?

As a follow up,

postconf -e bounce_size_limit=1
zmcontrol restart

This had the effect of including the bounce notification and headers,
but without the original email content (and no .eml attachment).
