==== REQUIRED BASIC INFO OF YOUR IREDMAIL SERVER ====

Hello,
I wish to add a simple disclaimer to all email received from outside our organization to the top of the email body, e.g.:

CAUTION: This email originated from outside of the organization. Do not click links or open attachments unless you recognize the sender and know the content is safe.

Can you point me in the best direction to accomplish this please?

iRedMail doesn't have such feature right now, but we're working on a new milter program to replace iRedAPD, and milter can access and modify mail headers and body, it has the capability to achieve this feature.

FYI https://github.com/iredmail/iRedAPD/issues/11

Hi deweydb,

Is prepending a short text in email subject good enough? for example, "[⚠️EXTERNAL] ".
