El Capitan killed my Gmail pop setup

hi, can you pl help me with the same issue on my google app account

Thanks for this post David.

I have now resolved my problem - unable to send out email from mail through my pop gmail account.

I have had to change settings in mail preferences to allow authorisation on outgoing mail which wasn't required previously.

Mail Preferences > Account information > Outgoing Mail Server (SMTP) > Edit SMTP server list > highlight smtp.gmail.com > click advanced > Authentication change from none to password

Hi

Prior to this update my mail did not require authentication to send out emails through my pop 3 gmail account. I wasn't getting the same error message as you but going into mail preferences and selecting account authorisation and entering my password for outgoing mail seems to have resolved my problem.

I found that use SSL option had been defaulted to on.

I was able to solve the problem by not using the connection setup wizard and solely using the Accounts tab under Preferences which allows you to view and edit a much wider set of settings under the advanced tab.

I'm having similar issues. I had all my gmail accounts set up as POP, but now all of them are IMAP, and it immediately started trying to download several tens of thousands of emails without asking me. Emails it HAS ALREADY DOWNLOADED when it was POP. And it created a bunch of folders I don't want. It has completely screwed up my mail. I just want things back the way they were.

Is there any way to fix the issue? Not just 'allow gmail to connect' but to get mail to return me to my previous setup? I don't have a problem with having to enter passwords as long as I'm in CONTROL, and not some upstart app who thinks it knows what I want better than I do.

This worked for me! Thanks

This one did it...fixed my wifes as well.

Have been having this trouble with hers for the last three upgrades.

Go figure.

I had 2 Stage Authentication set up for G Mail, using POP3. This meant that I was unable to see the option to "Allow Less Secure Apps." I turned off 2 stage authentication and was then able to see the option. It was already set. I received e mails from G mail to say that I had switched off 2 stage authentication and that I had now Allowed Less Secure Apps. Doing this solved the problem of having the password rejected in Mail.

I had the same problem with my POP Gmail and was able to fix it in a slightly different way – I have 2-step verification active, so the "Allow less secure apps" switch was not visible under sign-in & security.

Instead I selected "App passwords", and generated a new app-specific password. When I entered that new password into Mail, the POP account worked as before. (I suspect that the OS update meant that Gmail no longer recognized my Mac as the same device, so a new password was needed.) This may be preferable for people who don't want to change their security settings.

One annoyance, however: messages in my Gmail inbox were not preserved from before the system update, and after activation it only downloaded mail from the last several hours. This meant that numerous older emails I'd been keeping in my Inbox as a reminder disappeared from Mail.

I was able to retrieve a copy of the pre-upgrade Inbox from my Time Machine backup, and the messages still exist on the Gmail server, so nothing was permanently lost. But for anyone with a POP Gmail account who hasn't upgraded yet, I'd recommend moving any messages in the Inbox into a local mailbox before upgrading, to avoid the frustration.

Works for me. Thanks!!

Works! may thanks.

After installing El Capitan, I had the same problem with Apple Mail not recognizing my gmail password either. After reading this thread, I set my gmail to allow less secure apps, and that fixed it, although I also experienced the massive email download of thousands of old emails and it was a giant pain in the *** to delete all of them after I had to go through them and pick the mail I wanted to keep.

However I don't think turning on the "allow less secure apps" feature is much of a "fix", because I'm not wild about making ANYTHING less secure in this day and age. I hope there's a fix and I can switch that feature back off again.

I didn't have to turn on Allow Less Secure Apps to get POP to work. I just added the account with the wrong password to force it to give me more options so I could set it to a POP account and add the POP server. In Gmail I use 2 factor authentication and generated a App Specific Password for Mail. I did this for 5 gmail accounts. Allow Less Secure Apps is not even an available option for me since I have 2 Factor Authentication turned on.

Thanks for this thread - I was certainly bothered with the mail changes when I switched to El Capitan.

I made the suggested change in google security options, but nothing has changed in my mail program. The account still shows as IMAP, and I'm not seeing any place I can switch it to pop. Am I missing something?

Under my Pref > Accts page I see Acct Type as IMAP, and Incoming Mail Server as pop.gmail.com. In neither place can I make a change.

I tried adding a new account wondering if needed a separate account for POP, but mail won't let me add another, because I am already logged in to that account.

Do I have to delete then re-add? I am worried that doing that will royally mess up my inbox and folders.
