@RBoy, I appreciate the mention, but please don’t conflate the issues. I momentarily thought that I might have been affected by both issues, but was not. I am dealing only with properly-configured mail servers and am unaffected by this change.
I pointed it it since both issues started after the upgrade to beta4 (ruby upgrade from what I can see) and the both are related to email and there may be some correlation. It sounds like you’re still having trouble with the email jobs despite having a valid certificate.
If you are convinced they is no way they could be correlated I’ll remove the reference to your post, just DM me.
I don’t see a way they would be correlated but also not asking you to edit.
A setup on which thousands of emails flow smoothly and at the same time 30 consistently fail doesn’t sound anything like a certificate handling change.
