My Mail in Yosemite doesn't work!

I have similar problem but in my case I can't send or receive emails using gmail. Other email accounts (iCloud and MS Exchange) are fine.

Erik, I guess you can troubleshoot that with connection doctor.

I send mail with Gmail pretty fine.

What I have is a huge delay of getting the new mail from Gmail. I can see people have same problem with mail.app and gmail for many years. And none of the solutions work for me.

Erik, I was having the same problem. this is what I did and it appeared to take care of it. I must have had an old password in my "send mail server" that was causing my issue. BTW, I was getting the same error that you mentioned.

1. Open mail and then Open Preferences -> Accounts Information

2. Click on dropdown next to Outgoing Mail Server (SMTP) and click "Edit SMTP Server List"

3. Click on "Advanced"

3. Change "User Name" to "b...@customdomain.com" and re-enter your password (Password was my problem)

4. Click OK.

The dropdown should no longer say (Offline)

I've had this problem for days. I have tried several other "fixes", and this is the first to actually work. Thanks for posting this. All three of my Gmail accounts are working as expected.

I had the same problem, but I fixed it quite easily. In my case it was due too the 2-step-verifaction that I activated for Gmail. Shortly explained, you need to generate a (new) password just for the Mail App on your Mac. So, please try these steps:

1. Go to this page: https://support.google.com/accounts/answer/185833?hl=en

2. Click on the link 'App passwords'.

3. Login if required.

4. Now you will see a list with devices and applications that have a special Google password. If you see a password for the Mail App, delete it and create a new one.

5. Now put this new password in your settings of your Mail App.

This should do the trick.

I'm having a similar issue to Erik, my Apple's native mail app works fine when I am use my home wifi but refuses to connect via internet connections at coffee shops et cetera.

At the coffee shops, the wifi connects, I can browse the internet, but my mail boxes will not update. The "connection doctor" displays the infamous red dot. The error listed for Gmail cites an inability to connect to both the SMTP server and the IMAP server. iCloud also is unable to connect via IMAP server.

I've tried toggling SSL within the advanced connection options but get the same result.

The only difference between using the Coffee shop wifi and my home wifi is once I connect to the internet at the coffee shop, I have to click a "terms of use" verification box... I wonder if that could be interfering with my mail connection? If so, are there any ways to remedy the issue?

Thanks for the help/ideas!

Also don't forget, if you do have a 2-step-verification for your Gmail account, be sure to ALSO change the password in the Outgoing Mail Server settings as well. This was my problem.

1. After receiving the new app password from Google, Open Mail

2. Click on Mail and Go to Preferences

3. Highlight your Gmail account

4. Find the "Outgoing Mail Server (SMTP) section and click the drop down menu next to it.

5. Click the Drop Down menu and click "Edit SMTP Server List..."

6. Highlight the Gmail account at the top

7. Click the "Advanced" Tab below

8. Verify the User Name is Correct (I recommend putting username@gmail.com)

9. Enter the new generated password you received from google into the Password box.

This explained why I was Receiving my Gmail messages but I could not Send my messages. So be sure to put the password in both the "Incoming Mail Server" section and the "Outgoing Mail Server" section.

Hope this helps some of you.

Thanks for your input but it doesn't seem to help my problem. I have an o2, btinternet, gmail, me & iCloud email account but they all show the SMTP to be offline so cannot send emails. I can from my iPhone and iPad and also send direct from Gmail. Have tried various changes, as suggested, & re booted but all to no avail. Awaiting a call from Apple next week.

Changing the DNS (for example to the ones google provides: 8.8.8.8 and 8.4.4.4) worked immediately! Every other solution i tried, did not!

Pullober,
