How to fix the "Can’t verify the server" error on the Mac Mail Client

▶︎ Nothing is more frustrating for new (or old) Apple users than trying to get the Apple mail client working properly during its initial setup. The main thing that we are addressing in this article is the verification of the mail server during setup. The error “Mail can’t verify the identity of the server xxxxxx” often appears when working with the secure (SSL) settings for your mail client (where “xxxxxx” is the name of your server). This tutorial will walk you through the steps needed to make sure that your secure settings will work and your self-signed certificate is saved on your computer so that you don’t have to continually confirm the identity of your mail server.

The first step involves the setup of your mail client. If you are using the secure settings and you are seeing a window pop up that says “Mail can’t verify the identity of the server xxxxxx” then follow the steps below:

▶︎ Click on Show Certificate
▶︎ Next, click on the drop-down arrow where it says TRUST
▶︎ You will need to make sure that server listed in this message is the correct server. If you know it’s right, then click on “Always trust” next to Secure Sockets layer (SSL)
▶︎ Do the same thing for x.509 policy
▶︎ Next at the top of the warning window, you’ll see a checkbox with the line “Always trust ‘xxxxx’ when connecting ‘server'”. Click the check box.
▶︎ Finally, click on the button labeled “CONTINUE”

After you have finished the approving the certificate, you will need to make sure that both incoming and outgoing emails work. You might need to specify an outgoing mail server depending on how your email account is setup. Make sure to select the one that matches your mail server for your account. If necessary, repeat the steps above in order to make sure that the server settings are saved properly. You’ll know it’s working when you are able to send and email and receive an email without seeing the server verification window pop up.

  1. Watching YouTube for entertainment is fine but getting the solutions from the same is a blessing. Thank you so much for such informative video content.

  2. Hi Buddy, reached her in search of solution to the problem from last many months. I run GoDaddy mail account and it doesn't work on mail. Yes, it configures and also syncs well. but when I want to send the email a message pops which says "can't verify the account" I've tried plenty of ways to fix it, not sure whether I'm doing right or wrong but I appreciate it if you can help me. Thanks

  3. What if the "Show Certificate" button is not showing??

    I have quite a few email accounts and at least one gets to this point where I have to spend ages removing the account and adding it back in. Argh!!!

  4. Sorry but this does not work (for me, MAC OS 10.11.6)… after going through all the steps and approval, the problem comes back again. Currently the only work around for this intermittent issue is to press SEND several times, but eventually the problem will return.

  5. Help! It appears that in Mojave (the new Mac OS) that the "Show Certificate" button went away. (!) Now all you can do is click "OK" and you're stuck. Am I the only one seeing this? Any advice? Looks like "Keychain" could potentially have access to certificate permissions but I can't figure it out. Thanks…

  6. For me the fix was in the macOS keychain – however, it was a slightly different fix. Close System Preferences. Open Keychain Access (using macOS Spotlight search) and in the upper left, select "login" keychain, in the lower left, select "Certificates" and I had 2 (two) certificates listed "COMODO Client Authentication and Secure Email CA" and "UTN-USERFirst-Client Authentication and Email" I copied these out to my desktop (as a precaution) and then deleted these two certificates from the Keychain. I closed Keychain Access app and re-opened System Preferences. I can now add Google and Yahoo email accounts again from "Internet Accounts" preference pane.

  7. Unable to connect to email server to verify your account information no response from server ?

  8. Here's what's happening. I have my Facebook and other account connected thru (Internet Accounts) in the System Preferences Menu (Mac). I have been able in the pass to share Photos and other things to Facebook by just right clicking on them then hitting the share button, For some reason I haven't been able to do that for the last week or so. when I try (Internet Accounts) in System Preferences Menu tell me I need to put in my password. When I put in my password it says unable to verify Name & Password. So I'm not able to post to Facebook thru my (Internet Accounts). Can you help me repair this serves on my Mac?

  9. I'm getting a message from my (Internet Accounts) say Unable to verify User Name and Password when I try and post things to facebook from my mac Share button.

  10. Hi, thanks for making this video. I have a question, how if the 'show certificate' button didn't showed up? How to make that button appear?

  11. Thanks! Just to reiterate you likely will have to accept two certificates, one for incoming and another for outgoing (as was mentioned in the video).
