 Replying to [comment:27 dmsnell]:
 > that being said, I wanted to know if we can get something added to 6.9.1
 to reliably detect this fault situation and resolve it while we wait for
 the long-tail of updates to any upstream fixes which might get merged.

 Ok, I got you. I've added a failover in case this is not sorted on time.
 If this gets merged, I will make sure that it gets deleted on the same
 patch as the PHPMailer next update.

 @jorbin I was thinking of creating a separate ticket that closes this one,
 because if it's a PHPMailer update, it will belong to the `External
 Libraries` component.
