Unable to connect to p3plcpnl0583.prod.phx3.secureserver.net 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)
Username: xxx@xxx.xxx
Password: Use the email account’s password.
Incoming Server: p3plcpnl0583.prod.phx3.secureserver.net
IMAP Port: 993 POP3 Port: 995
Outgoing Server: p3plcpnl0583.prod.phx3.secureserver.net
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.

Hello 

 

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.

ZulWeb,

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.

@GetSubs

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)

Re: Unable to connect to p3plcpnl0583.prod.phx3.secureserver.net SMTP Port 465 from my cpanel email

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.

Re: Unable to connect to p3plcpnl0583.prod.phx3.secureserver.net SMTP Port 465 from my cpanel email

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.
