Conversations not grouped by subject in El Capitan mail

I get emails from Fail2Ban on one of the web servers I manage. Each one has a subject of the form "[Fail2Ban] WordPress: banned 45.41.92.66". They're all the same except for the IP address ("45.41.92.66"). Before El Capitan, all the messages with identical subjects, in this case the same IP address, were grouped into a conversation, with a handy dandy counter plainly visible. That made it easy to see which IP addresses were attempting logins so often that I needed to ban them permanently, not just for 10 minutes at a time, as my Fail2Ban is configured to do.


El Capitan mail organizes messages by actual conversations, i.e. messages that are responses to an original, but it doesn't group emails with identical subjects that are not actually part of the same conversation. This is likely correct for many email conversations, but it doesn't work for these Fail2Ban messages. I would love to have a preference to select the old way of grouping by only the text in the subject.

The removal of this feature has inspired me to prepend the subjects of as many automated emails as I can with "RE: ". This enables threading across platforms: Windows or Mac, Outlook or Mail.


One issue I ran into doing this, is if the subject is exactly the same, it will put them all in a single thread, instead of separate them by sender like Mail used to. Most notably, HP server SNMP traps. To fix that, I added the hostname of the server to the subject of those too. Now everyone on my team has their automated emails threaded, regardless of OS or application. For the stuff I can't change the email subject for, like hardware appliances, I'm debating having the mail server rewrite the subject before its delivered.

The option still "works", since messages with "re:" in the subject are grouped into conversations. They just decided that messages from the same sender with the exact same subject line are no longer "conversations".


I installed the 10.11.1 update that was just released. I don't see any change to the behavior for conversations. 😟

Yeah, I could go do that, for the hundred's of notifications that I have setup, but why?

In what idiot's infinite wisdom would they decide to remove a feature that was working?

Not to mention, the same thing is happening on iOS now with 9.1


Is there some way to configure it in some magic config file at terminal?

HeII, I am ready to find the previous version of Mail and drop it over this version...but not sure that will work.

Honestly, this is the most compelling reason here, and I never looked it that way.


OSX Mail provided the SINGLE way to do this across ALL MAIL CLIENTS.

It had been doing it for quite a few versions that I know....


...and of course Apple removes it, and if you look at this thread, folks knew during the beta.


Yet again, apple gave zero shlts about it.


I can't believe the iPhone crew is not expoloding about it, since 9.1 is doing the same there.....


Total fail on Apple's part.

I too would downgrade if possible. There is nothing in the new version that makes up for this the way I use my computer. I haven't seen anywhere that Apple even remarks as to whether this is a bug or a feature that they just changed.


I saw where somebody asked if there was another email client that offers this feature but never saw and answer. Does anybody know?
