    On our older servers which use cPanel (Ocean, Aus, Acadia, Eagle, Banshee, Friday) there is presently a bug in which you are sometimes unable to send email due to a "condition check lookup defer." This bug was introduced with a patch that fixed 21 vulnerabilities in Exim, and it's fix is currently part of the cPanel 98 release which is not yet released. We're stuck in a difficult situation because our options are:

    1. Deal with it until patch release.
    2. Migrate users from the cPanel platform and accept the fallout.
    3. Revert to vulnerable packages (not an option).

    The complaints for #1 are lower than we've documented in previous migrations from cPanel to our newer platform. The only logical solution is #1, it is by far the lesser evil. We'd like it to be otherwise, but all cards on the table this is the best choice in front of us right now.
