Mail not working in El Capitan

After installing the GM onto my 2009 macbook pro, running Mavericks, Mail will only send and receive mail if I've enabled "insecure authentication allowed" in Mail's preferences. IMAP & POP accounts both have the same problem. I then tried to reboot El Cap & I got a kernel panic on the opening screen.

Obviously this keeps me from using El Cap. If I had been able to reboot back into El Cap & then been able to use mail without the risk of sending my password to my ISP insecurely, that would've allowed me to use El Cap securely and as I'm looking to purchase a new 27" Imac in the next couple of months for my business I'll have to seriously reconsider this purchase because of this problem.


Anyone else seeing this or heard of it and what the fix might be?

PS: UI is quite slow when using the trackpad to return to the last page visited in my browser.
The shifting of the present page to the right to reveal the last page visited takes literally over a second.
In Mavericks this "trick" doesn't exist and going back a page is pretty much seamless.

Repeated kernel panic could indicate hardware issues.

Test Mail in a new User.

CREATE A NEW USER
Go to System Preferences --> Create a New User in Users & Groups.
Switch to the New User by logging out under the Apple in the Menu Bar.

Open Mail
Add one of your accounts and test.

If you don't have issues in the new User this indicate problems in your current User.

Mail switched to a new format in El Capitan. Previously your messages were stored in the V2 folder in Mail. El Capitan uses a different type of database and stores your messages in the V3 folder. Often the only fix is to start clean in El Capitan. Your test in a new User will verify what steps you need to take next.

Hi DofO,
Years ago I had a corrupted Mail file that required starting from scratch by ditching all my mail folders.
I hate to think that I'll need to do that again just because of an OS update.
In any event, I'll give creating a new user a shot in order to eliminate that possibility.

As far as the kernal panics, it seems that more than a few folks are experiencing them so the odds that
we're all experiencing hardware problems seems unlikely. Then again, this is a 2009 laptop I'm using, so who knows?

If the New User Mail account works without issue, I'll at least have a better idea what my options are.

Thanks for the reply!

I solved my El Cap Mail problem.
Instead of upgrading to El Cap directly from Mavericks I first upgraded to Yosemite.
After the Yosemite install I checked Mail and it worked fine.
I then installed El Cap over Yosemite and now Mail works perfectly with all settings transfered over perfectly.


I haven't tried rebooting to see if I'll get a kernel panic just yet.
That I'll do later after I've spent some time checking out the new GM and whether I have any apps that aren't compatible.


As far as the UI lag in Safari when returning to a previous page by swiping the trackpad, that's fixed too.
My 2009 macbook pro is able to handle it smoothly. That said I still prefer how Firefox works in El Cap to Safari.

I'll update this post with an edit when I do a reboot.

Same here. Just updated to El Cap and Outlook just hangs and hangs.

Have you tried deleting your Mail accounts in Mail Preferences & in System Preferences & then creating new accounts from scratch? That fixed the problem I was having with Mail.

Similar Problems here, IMAP and SMTP did not work. After changing the "description" field to something simple it worked. I Suppose it has something to do with the "@" symbol which I had used before in the "description" field.

I'm not technically competent to make real sense out of the super-long error report.

In short, after installing Cap and restarting, every time I try to open Mail it crashes within 2 sec. (no exaggeration). I'm a manager in a strongly pro-PC company--the only reason I get away with using my Mac Air on the company net is because I'm usually rather productive. But spending nearly half a super-busy Friday trying to figure this mess out did not help my reputation:(

After repeating my "F*** Apple, f*** Apple" mantra a few times I DL'd Thunderbird, an app I haven't used in years, and set up my most important accounts--it worked like a real trooper! (Tho I had to wade thru spam without Spam Sieve)

I've been an early adopter of every OS since 7, with only a few small hitches (usually none) after installing them. This may be the first time I "go back" to the previous OS. Will try the new user test, and with luck Apple will put out some updates this weekend...

Tried setting up a new user account and added a few e-mail accounts in Mail. Worked fine, could open and close several times. Apparently there's something in my old Mail settings that Capitan doesn't like. Think I'll just do a clean install--takes a good portion out of a beautiful weekend, but sometimes going from a fresh OS clears out lots of cobwebs...

Went into the Library's Mail folder to see if anything might be tripping up Capitan. Noticed a mailbox folder called "RSS" with only something from Apple in it; on a whim deleted it. After that, Mail opened and asked to import my mailboxes. When I started doing that, the dialog box showed the time it would take as several hours; since I did a TM backup just before then, I deleted the data inside the mail boxes and then went back to the 'import.' Now Mail is working fine. Can't guarantee it'll work for you, but if you keep getting Mail crashes, you might try removing that RSS mailbox from your Library folder.

If these steps work, what would you suggest for next steps. I deleted original internet accounts in the original user but still cannot access mail. Appreciate your help.

My Mail is acting up also. It will not receive any emails and my 27 Imac (2010) slows to a crawl.
I looked at the "Activity Monitor" and mail had taken 95% of all available memory.
It does not download or display any emails. This sux!!
How do I go back??

the problem(s) I am having with Mail in El Capitan is

a) when I first launch Mail, it just sits and does nothing and I have to force quit it and relaunch to get it running

b) I have 32G memory on my machine, and when I launch Mail, it eats up almost all of my memory available

I am looking for solutions…..

I have kernel panic mega and Apple are trying to sort for a week now.
They have posted a solution in their support pages but it has not worked for me.
Any help gratefully received.

Thank you Apple. Now I can set up dozens of mail accounts, anew. That was Very Smart and proves the down-dumbing process of your engineers. If Steve was still around he'd kick all your wonderful bottoms. But now it's the "people" who will think twice, again, if they shall stay with Apple.
