Unable to connect to SMTP Port 465 from my cpanel email

I'm no longer able to send email through my GoDaddy cpanel email account.  I'm using the following information (as provided by GoDaddy for manually configuring) to configure my Apple mail (I've x'ed out my Username in the below.  I assure you, I am using the correct info in my mail configuration):

Mail Client Manual Settings

Secure SSL/TLS Settings (Recommended)
Password: Use the email account’s password.
Incoming Server:
IMAP Port: 993 POP3 Port: 995
Outgoing Server:
SMTP Port: 465
IMAP, POP3, and SMTP require authentication.


My connection to the Incoming Server completes successfully when I use the POP3 Port 995. 

My connection to the Outgoing Server fails.  Failure information from the Mail Connection Doctor is:

"Could not connect to this SMTP server. Check your network

connection and that you entered the correct information in the

Account preferences. Also verify that the server supports SSL. If it

does not, deselect the "Use SSL" checkbox in the Advanced tab of

Account preferences."


I'm running OS X El Capitan 10.11.6

Apple Mail v9.3 (3124)


Please advise what I need to do to get this working again.



This morning my email was able to send again.

Check your smtp to see if it's working again. They probably applied another cPanel update and that included an email fix. My email is configured exactly as they instructed on their setting page.

Let us know if all is working for you.

The Email Setup Center is a one-page view of your account settings and getting started links. You can access the Email Setup Center from the Workspace Control Center, or your Workspace webmail. Click Tools, and then select Email Setup Center. If you only see Incoming server (POP3), your email plan does not support IMAP.

thanks very much for your reply.  Unfortunately this did not resolve my issue.  It works perfectly for the Workspace email account I created but it does not work for my web hosting email account.  My web hosting account provides for 99 email accounts and GoDaddy provided the configuration information for these email accounts as outlined in my original post.

My web hosting email account used to work without issue and only recently (last month or two) has stopped working.


At this point I'm ok to go forward using the Workspace email but I am curious as to why my web hosting email stopped working after several years of using it with no issues.


In your cPanel console, what is your 'Email Routing' set to for your domain? Just curious!

I have the same basic problem. My routing is set to "local". Everything is fine if I use "non-SSL" settings, but trying to use secure "recommended" 465 port returns a 550 error. This problem is also pretty recent for me as well.  I know that my DNS settings are all good. I'm even able to use "auto configure", but if I do that it makes everything Non-SSL by default. I'm not on a mac though, but it's the same basic issue.


I'm wondering if cpanel is somehow forcing a TLS version now that Outlook 2010 doesn't support? (that's the mail client with the connection problem)

I just recently experienced the exact same thing. Specifically, I can receive POP3 port 995 but not send SMTP port 465. I'm also using...


OS X El Capitan 10.11.6
Apple Mail v9.3 (3124)


It's definitely an issue with SSL and certs. My guess is that the SMTP server cert expired and/or is no longer providing a valid one. GoDaddy won't help at all, and is keen on getting everyone off cPanel email. A rep literally told me—direct quote—"If we could block cPanel email, we would." Congrats—you did.

I am now retracting any suggestion that GoDaddy is at fault (other than their general unwillingness to help with cPanel email issues).


I switched email clients to the latest version of Thunderbird, and everything worked as it should, suggesting that the issue is entirely with v9.3 (3124) of Apple's Mail app.




Hi @footai,


Welcome to the Community!

Please use the instructions here to set up your email client for cPanel email plans. There are several port options you can try, as some ISPs favor ports specific to their services.

Same problem here with El Capitan and Apple Mail client.


Spoke with two techs, one from cpanel, they never heard of this problem. One tech didn't know what a "El Capitan" was.


Not a TLS issue because Thunderbird works fine. Also seems to work fine in newer MacOS versions and no problem sending email from iOS with exact config.


Almost like they are blocking the user agent for Apple Mail 9 or some type of handshake issue. Looked to see if that could be changed but its somewhere in the frameworks files. I tried configuring with plain text no ssl and even that doesn't work.


IDK if you noticed but cPanel has some bad links and when you click on email it has to redirect to another page. Hopefully with another cPanel update they will fix this issue. For now I'll have to use thunderbird as imap to send emails and cc myself and Apple Mail will receive a copy and I can place that in the sent folder.


If anyone figures out a solution let us know. I'll check back later.

Just adding a "me too" to this discussion, though my server is  I am also on El Capitain using Apple Mail and I don't think there was any update on my OS when this stopped working.  I too was told my Go Daddy support that the cPanel email I have had for many years isn't really a product and it just comes with cPanel and they wish they didn't have to include it - I should be paying them $12 per email address to get something that is actually secure.  Seems they are trying to leverage more sales. 

But, I will confirm that my non-working email clients are the AppleMail and also Windows 10, but that Thunderbird works and also IOS, pointing to either a specific blocking of either client or that particular protocol.

Since this is my primary email, I will have to find a new hosting service if this doesn't resolve.

A little more... I'm not sure this is helpful or a real solution, but I ran a test to help isolate the problem.  We all know there have been no software updates to OS X 10.11.6 and Apple Mail for quite some time, yet we have all experienced the recent failure of GoDaddy email.


So, I took a second Apple Mini I was running with 10.11.6 and configured the mail on it.  Not surprisingly, it didn't work either.  I then upgraded it to HighSierra 10.13.  Without any other changes - meaning using the same server settings for name and ports, it just worked immediately.


My theory is there is some subtle protocol difference in 10.11.6 that Go Daddy decided to discontinue.  So, our choice is between discontinuing 10.11.6 or discontinuing GoDaddy.


This morning my email was able to send again.

Check your smtp to see if it's working again. They probably applied another cPanel update and that included an email fix. My email is configured exactly as they instructed on their setting page.

Let us know if all is working for you.

Yes - miraculously fixed itself!  Thanks for noticing and posting.  I had stopped checking.
