Here is what I have tried so far, sequentially...

Reset PRAM and VRAM

Reset SMC

Reset Startup Disk and Sound prefs

Safe mode - hard to tell if effective because sometimes it takes days to crash!

Apple Hardware Test - OK

Repair Disks and permissions

Reinstalled OSX from Recovery disk

I have an Etrecheck report that I will post below in advance...

Etrecheck report

Many thanks in advance for any help that can be offered!

This may also be applicable: If Mail unexpectedly quits when viewing certain messages ...

Others that may offer helpful suggestions:

Troubleshoot email problems in Mail on Mac - Apple Support

Rebuild mailboxes in Mail on Mac - Apple Support

I realize the problem may not occur for several days at a time, which makes troubleshooting difficult.

It's possible an incompatibility exists between Mail and one or more of the email services you're using. There isn't much you can do about that, except to continue to send those crash reports to Apple when they appear. Apple doesn't respond, but if they contain information useful to them they may address it in a future macOS update.

EtreCheck is a simple little app to display the important details of your system configuration and allow you to copy that information to the Clipboard. It is meant to be used with Apple Support Communities to help people help you with your Mac.

Pastebin is a good place to paste the whole report...

Or use the paperclip at the bottom of a Reply to attach the full report here. :)

Workable but harder for me to work with...the Note tool on the bottom of this editor's toolbar, as shown in the image, to copy and paste the output from EtreCheck.

Hey BDAqua,

So far so good!

...can I ask how you determined that this might be a problematic file from the information that I posted? I am keen to learn how I can learn to decipher some of these logs that are generated.

Thanks

Great to hear Phil, the great etrecheck listed that file in the Cleanup: section, which means it was running or trying to run, but to no avail as it's other files were removed, so it was wasting resources, sometimes those .plists in the Cleanup: section have minimal effects, other times they may hog GPU, RAM, & all other resources as they keep asking the OS tho reserve Resources over & over.

Always delete the .plists in the Cleanup: section & restart. :)

Hi BDAqua,

It seems to me that I have the exact same problem.

It started about a week ago. I have the feeling that mail crashes most of the time, while im closing a draft without saving. But it also happens when im not actively using mail.

The only difference in our Problem Report I can find (without knowing too much that stuff) is:

Application Specific Information:

*** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[__NSArrayM objectAtIndexedSubscript:]: index 9223372036854775807 beyond bounds [0 .. 3]'

terminating with uncaught exception of type NSException

abort() called

Are these bounds in the brackets relevant for an issue like this?

I couldn't find any info when this mail version (11.5 (3445.9.1)) got released. Anybody got info about that?

Pretty annoying, but besides that my MacBook Pro mid-2010 still runs like a Usain Bolt ;-)

index beyond bounds is usually a borked database...

Safe Boot from the HD, (holding Shift key down at startup), does the problem occur in Safe Mode?

Safe mode attempts to repair Disks & clears lots of caches, so if Safe Mode works try again in regular boot.

Assuming all your Mail is IMAP & not POP, highlight Inbox, from Mail's Mailbox menu choose Rebuild.

I have been monitoring it but I do not think it is RAM t this point. I run a multitude of other softwares and it is only this same thread that crashes in my Mail program.

...oh, well. Hopefully something will come to light.

Safe mode attempts to repair Disks & clears lots of caches, so if Safe Mode works try again in regular boot.

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

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.

Yes, Mail crashing in High Sierra was making me crazy and i tried a lot of possible fixes, rebuilding, deleting preferences, etc.

This seems to work, go into Accounts via Mail or System and delete all the internet accounts.

My computer crashed, which I took as a good sign.

On reboot, reinstall only the accounts you must have. I did iCloud and Google.

There was a number of old unused accounts like GameCenter, and kids expired/dead accounts.

It seems stable now.

I'm not very good at deciphering those kind of reports.

If you'd like more help start a new topic & post an EtreCheck is a simple little app to display the important details of your system configuration and allow you to copy that information to the Clipboard. It is meant to be used with Apple Support Communities to help people help you with your Mac.

I do the same thing..."I went into System Preferences, Internet Accounts and deleted and re-Added my Gmail accounts; re-booted and opened Mail successfully."

Problem about 1-2 days later crashes again and only TEMPORARY solution is to delete gmail account and add back in Mail.

Works for 1-2 days and "ground hog day" again.
