--- Comment #4 from bugzilla@freshdot.net <bugzilla@freshdot.net> ---
I'd like to re-open this bug, as it is still present in current Exim and Exim
going back to 4.71 at least. Situation is as described in the original bug
description.

A test case was set up using one of my vanity domains to aid in debugging this.
Compare the output of:

# exim -bt foo@onecname.bokhard.nl

vs

# exim -bt foo@twocname.bokhard.nl

Yet, more CNAMEs do not change the destination domain further, eg '-bt
foo@threecname.bokhard.nl' does the same as 'twocname'.

I wholeheartedly agree with [Comment 1] and not using CNAMEs, unfortunately i
do not control the internet.

This issue has recently been discussed on the exim-users ML,

Here's a test with those DNS records, sample configuration and full debug that
reproduces it with the latest Exim:

twocname.bokhard.nl. IN CNAME onecname.bokhard.nl.

bokhard.nl. IN MX 100 mxfallback.freshdot.net.
