#1028 mod_carbons [hg 3092ae96c1f0] not forwarding message errors
What steps will reproduce the problem?
1. Send a chat message to a non-existent JID
2. Message gets CCed to your other client
3. Receive error bounce
4. Error bounce will not be CCed to your other client
What is the expected output?
According to XEP-0280, "A <message/> is eligible for carbons delivery if it is of type "error" and sent in response to a <message/> that was itself eligible for carbons delivery (something something server complexity)"
Therefore, the error bounce should be carbon-copied, so that my other client can see that the message did not arrive.
mod_carbons in trunk should be doing this since around https://hg.prosody.im/trunk/rev/f7e8d299513f
if someone wants the community version to do so then they are encouraged to backport the relevant changes, or maybe move to the core version.
