Bug ID: 2568
Summary: Error messages (DSN) are inconsistent and misleading
Product: Exim
Version: 4.93
Hardware: x86-64
OS: Linux
Status: NEW
Severity: bug
Priority: medium
Component: Delivery in general
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
In Exim 4.94.RC0 error messages (DSN) are sometimes inconsistent and
misleading.
For the following example the aliases file for domain example.com contains:
a: b, c
Adresses [email protected] and [email protected] does not exists. If a mail is
sent to
[email protected] the error message (DSN) looks like:
-------------------------------
[...]
Content-type: text/plain; charset=us-ascii
This message was created automatically by mail delivery software.
A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:
[email protected]
(ultimately generated from [email protected])
Unknown user
[email protected]
(ultimately generated from [email protected])
Unknown user
[...]
Content-type: message/delivery-status
[...]
Action: failed
Final-Recipient: rfc822;[email protected]
Status: 5.0.0
Action: failed
Final-Recipient: rfc822;[email protected]
Status: 5.0.0
[...]
-------------------------------
The "text/plain" part is correct and as expected. But the
"message/delivery-status" part does not show the failing non-existing addresses
but the parent address twice. This is neither useful nor the "final recipient".
The "message/delivery-status" part should look like this:
-------------------------------
Content-type: message/delivery-status
[...]
Action: failed
Final-Recipient: rfc822;[email protected]
Status: 5.0.0
Action: failed
Final-Recipient: rfc822;[email protected]
Status: 5.0.0
-------------------------------
git bisect points to commit 436bda2.
