    I've been having issues getting a proper testing environment setup to replicate this behavior. Could you submit a ticket to our team so we can do some additional work on this for you? Please let me know the ticket number once you've had a chance to do that so I can follow along on my end.

    @assid2 - at this point we haven't been able to reproduce the issue. If you have a server where you're experiencing the problem, please submit a ticket to our support team so we can check this out.

    You should be able to re-create since I believe it can also be the reason why you have this bug :

    This has now been assigned to a team so they are going to explore if it's something we want to adjust or just remove. I'll be sure to keep this thread updated with my findings.

    Update - this has been resolved with the following note in the rpm changelog: Add flag file for restoring old sort bias for ipv6 case HB-6385: Considering that by default we'll likely want to keep our patched behavior (given the last patch for this was in the other direction " you could enable patched behavior with flag file " was reverted), we'll use a flag file (/var/cpanel/exim_ipv6_sort_bias) for restoring the "original" behavior.
