@cPRex I'd love to upgrade to Edge but it says it's not recommended to use it in production, and also it'll be hard to go back to "Current" next time. Already that "Release" I can't take it anymore because I can't go back to an older version, I should have taken that, it would avoid falling on bugs like that :/
The email bug has been there since January 21, for almost 10 days!

What's happening with the update? We need it right now as this is having a huge impact on every email our server sends.

Is there anything we can do to work around the issue, such as rolling back to a previous version, until the update is moved into the CURRENT branch?

There is never a supported way to downgrade cPanel.

Servers being used in a production environment should at least be on Release or a more stable tier, and this issue only affected Current and Edge. The best thing to do at this time is to wait until the fix moves into Current.

I understand that, but considering this issue became apparent on 25 January, why wasn't the CURRENT branch paused or rolled back to avoid anyone else updating to the CURRENT branch becoming affected by this issue?

As for production servers using RELEASE or STABLE, the description you've used for the CURRENT branch within the Update Preferences isn't clear enough as it does not provide any warning for production servers like the EDGE branch does.

When will the update be moved over to the CURRENT branch?

There isn't a way to do that as the cPanel software can't be downgraded. We did make the case high priority, meaning that Current wouldn't get another update until this case was resolved.
I understand, but could we manually update just Exim-4.95 via the EDGE RPM of Exim? . I guess that the patch for this issue is on that RPM.

I have created my own workaround - by downgrading Exim using 2 commands. We are now able to send emails from our cPanel server!

Code:
wget http://httpupdate.cpanel.net/RPM/11.98/centos/7/x86_64/cpanel-exim-4.94.2-4.cp1198.x86_64.rpm

yum downgrade cpanel-exim-4.94.2-4.cp1198.x86_64.rpm
Obviously I am now expecting cPanel to say this is not supported, BUT IT WORKS!!! Or at least is does for me!

EDIT:

In addition to my last reply, I have also had to run the following command to resolve the "permission denied" errors I just noticed in the exim_mainlog:

Code:
chown mailnull.mail /var/spool/exim/db/wait-remote_smtp
I am no longer seeing those errors and everything within cPanel/WHM is still operating as expected.
