Bug ID: 2013
Summary: Bounce message missing Diagnositic-Code for
unrouteable addresses
Product: Exim
Version: 4.86+ HEAD
Hardware: x86
OS: Linux
Status: NEW
Severity: wishlist
Priority: medium
Component: Delivery in general
Assignee: ni...@exim.org
Reporter: chir...@spamexperts.com
CC: exim-dev@exim.org
Overview:
When a bounce message is generated by Exim because the address is unrouteable,
e.g because of:
- "all relevant MX records point to non-existent hosts"
- "Unrouteable address"
The bounce message generated is missing the "Diagnostic-Code" field is missing.
This generally is not a problem but we've encountered some other services that
rely on header being present. (E.g. O365 is only showing the status code in
this cases with no extra details)
Steps to Reproduce:
- Send email to an unrouteable address e.g. t...@bogus.example.com
Results in:
