Apple mail freezes continously - "Dispatch Thread Soft Limit"

I have the problem that Apple Mail has become stuck and freezes continuously, I've made a snapshot that I attach here. I do have many accounts in my mail... Is there a way to fix this?

Hmmm, something is trying to do too much at once, hard to tell if it's corruption or what, or where the corruption is even.


Safe Boot, (holding Shift key down at startup), does the problem occur in Safe Mode? Could take 10 minutes.


Safe mode attempts to repair Disks & clears lots of caches & loads safe Drivers, & prevents loading of 3rd party extensions, so if Safe Mode works try again in regular boot.


To find out if it's system wide or user specific, try this...


Open System Preferences>Users & Groups, unlock the lock, click on the little plus icon, make a new admin account, log out & into the new account.


Does it work in the new account?


If still no good Disconnect from the Internet, then start Mail, look for the last rec'd eMail.


Does Mail crash if no internet?


Quit Mail & login to your WebMail in a Browser, if possible delete any later eMails there after the last rec'd one on the Mac.


If you have no POP accounts & they’re all IMAP accounts then in Mail’s Mailbox menu choose Rebuild.


Do you have a Time Machine backup to Restore to/from?
