"Mail can't verify the identity of" error
Email Client: Mac Mail
Error Message:

Mail can't verify the identity of "mail.domain.com".

The certificate for this server is invalid. You might be connecting to a server that is pretending to be "mail.domain.com" which could put your confidential information at risk. Do you want to connect to the server anyway?

cant_verify_identiy

Solution:

When Mac Mail connects to your server, it by default attempts to connect using a SSL connection. On shared servers, the SSL certificate will look similar to secure108.inmotionhosting.com. Mac mail is throwing an error because it is not seeing a SSL certificate for "mail.example.com", and instead it is seeing the secure108.inmotionhosting.com certificate. This is common, and it is safe to ignore. Click "Connect" to ignore this message and continue.

To verify it is an inmotionhosting.com certificate, click "Show Certificate", and you should see it listed.

This message was helpful in that it gave me some clues to figuring out how to stop getting the error.  The setting for the email were off in that the SSL and ports needed to be changed.

Hello Mary,

Thank you for contacting us today. I'm glad you were able to fix the error. You can view your specific email settings in cPanel at any time.

Changing the Port/SSL setting can often help, especially if you are on a network that is blocking ports.

If you have any further questions, feel free to post them below.
Thank you,

I am continuing to get this invalid certificate message and it will not allow me to connect.

When I click on "show certificate" I get a message that the certificate has been revoked.

I can't seem to get rid of this.  Thedate and time on my computer are correct.

Hello Tobi,

Are you connecting to a shared server as in the article? Have you tried the suggestion the article gives? If so, which server are you attempting to connect to? What are your port settings?

Kindest Regards,

Having created various emails and pressed 'send' each time, the emails sit in the Outbox rather than being sent. I then have to quit Mail. Wait a minute. Re-open Mail. See error message as above and apply the solution proposed, of simply pressing 'Connect' which works perfectly and all the emails go.

The Question is, how do I verify the identity of “mail.domain.com”   

What can I do to change settings so that Mail knows the mail.domain.com is ok and Mail will then send each email as I complete and send it, rather than having to close and re-open Mail in order to send eMails.

Hello Richard2014,

The problem is well-described above. You simply have to to re-enter the correct email server information and then approve the server. Apple's mail client will say that it can't verify it, but the problem exists because Apple's mail client is expecting the use of SSL, when it may not actually be in use. You are welcome to use the SSL version of your email server settings. Find your email settings by going to How to find my email settings. This will give you BOTH of the email server settings that you can use (the SSL and NON-SSL settings). The servers are legitimate because you can access email and your website from them. You can also use PING or TRACEROUTE diagnostics in order to determine what server your URL is going to. These will result in an IP address that you can further look up on the internet if necessary. If you use the secure email server settings, then you can verify our SSL settings by using a third-party website such as SSL Checker from SSL Shopper or any other websites that can verify SSL certificates. The SSL Checker I have linked simply requires a server URL. For example, our secure servers use the format of: secure###.inmotionhosting.com (where "###" is the server number).

I hope this helps to explain your question about verifying the server. As I said earlier, you would need to re-enter the values in the Apple Mail client in order to "verify" the server settings that you are using. If you used the "mail.domain.com" settings (where domain = your website domain name), then the Apple Mail client is basically unable to verify it simply because it expected the use of an SSL certificate which is not always required for these settings. You can still force the Apple Mail client to use these settings (the non-SSL server settings) by simply verifying the server in the dialogue box that pops up to verify the server. If you have any further questions or comments, please let us know.

Arnel C.

I know apple mail does not work with Microsoft Exchange on Microsoft Server 2003 since a few years ago. 

I have just purchased a new mbpro early 2015 and was hoping that something has been done to resolve the problem. I am still using the same microsoft exchange on Server 2003. 

Does anybody know if the situation has change or if there is a way around the problem?? Any light will be highly appreciated. 

thanks, 

Michael

Hello Michael,

Thank you for contacting us. On Apple's Support site, they have a guide on how to Use Microsoft Exchange (EWS) accounts in Mail on your Mac.

There it states "Your Exchange server must use Exchange Server 2007 or later. "

So, it does work with exchange, but unfortunately not your version.

Thank you,
John-Paul

Just bouth a used Macbook Pro.  I can't connect to exchange.  I get this error:  The Exchange server ####.&*^%$&%.com is not responding.  Try checking the network connection, and that serveer name is correct.  Otherwise, the server might be temporarily out.   The connection is good and the server name is correct.   I hit continue.   It sets up the mail, but does not sync it.   I also get a error regarding the secuity certificate.   What can I do?

i think you should first find out what version of the the Microsft server you are running. You can give up trying if it is Microsoft server 2003. The apple OS (at least the last few versions) will not support it.

Hello Dawn,

Thank you for contacting us about setting up mac mail. I recommend trying your alternate email settings. For example, if you are using the non-SSL settings, try using the SSL settings instead (or vice versa).

This will rotate the port settings, and rule out port blocking on your local network.

If your problems persist, review the mail logs for errors, or record of transmission. If you are on a shared server, Live support can help you with this.

Thank you,
John-Paul

Hello Davee,

Thank you for contacting us. I looked at the smtp settings (I marked them out for security purposes) listed in your error, and the ssl does not appear valid.

I recommend contacting your email host, so they can investigate further, and correct the issue.

Hello Dana,

Sorry for the problem with Mac and your Exchange server. One thing to bear in mind is that Mail clients do NOT maintain a continuous connection with the mail server. They will connect, transfer data for email, then disconnect. We need more specific information about the versions of software you're using (such as what users are using on the Macs to connect to your Exchange server), in order to provide more specific information. Your SSL query depends upon whether or not you are using an SSL certificate. Since you are using a Windows Exchange server, we can't verify that for you. You may need to check with your email administrator. I did look around to see if there are reports where Macs are continually losing connection with Exchange servers and I found this post. Check it out and hopefully, they have the information needed to correct your problem.

I hope this helps to answer your question, please let us know if you require any further assistance.

Regards,
Arnel C.

I got so sick of this popping up on my email. This is what I did:

  1. Go to macmail
  2. Select preferences
  3. Select the account that's generating the message
  4. Click on Advanced tab
  5. Unselect SSL and make sure you leave it 993 as the port
  6. Save

It's probably full of issues doing it that way, but it got rid of that stupid message everytime I sent a email.
