outlook unknown certificate and php_network_getaddresses

[jclins]

Hello everyone, I'm having problems with the email system. It is working, receiving and sending email by the roundcube (including DKIM and SPDIF ok).

If I try to connect through Outlook 2016 I get a certificate error message:
https://prnt.sc/k8d021

When I send email with the application in php I get the error message: php_network_getaddresses
https://prnt.sc/k8cznn

In theory, the server is configured correctly:
https://prnt.sc/k8cydk

Anyone have any ideas how to fix it?

the first issue is related to hostname certificate so you need to install some valid certificate.
By default in cwp if you have a working A record set for your hostname when saving hostname CWP will automatically install free autossl.

for other issues in php try to check your application and requirements for it

Sorry my delay. I'm a newbie. I reinstall all 3 times and none of them worked.   

My footerprints:
0-Change MYDOMAIN.COM NAMESERVERS to NS1.CENTOS-WEBPANEL.COM and NS2.CENTOS-WEBPANEL.COM
1-change hostname for MYDOMAIN.COM
2-install cwp-el7-latest
3-Enable Firewall (IP:2030/admin/index.php?module=firewall)
5-Verify rDNS/PTR and Hostname (IP:2030/2030/index.php?module=change_hostname)
6-Create MYDOMAIN.COM in "Free DNS Manager"
7-I wait 8 or 12 hours for  DNS propagation
8-create NEW ACCOUNT  for MYDOMAIN.COM with AutoSSL checked (IP:2030/admin/index.php?module=new_account)
9-Enable DKIM (IP:2030/admin/index.php?module=dkim)
10-Copy DKIM key to "Free DNS Manager"
11-Create sPDIF in "Free DNS Manager"
12-Create _dmarc  in "Free DNS Manager"
13-Check SLL (https://www.sslshopper.com/ssl-checker.html?hostname=MYDOMAIN.COM)
14-Create email (IP:2082/iddircom/?module=email_accounts)
15-Configure email in Outlook

What's wrong??? snifff

I read again and I make a mistake when I wrote first step, the correct is:

1-change hostname for SRV.MYDOMAIN.COM

the first issue is related to hostname certificate so you need to install some valid certificate.
By default in cwp if you have a working A record set for your hostname when saving hostname CWP will automatically install free autossl.

I have:
srv1      0      IN      A      IP-ADDRESS

It's correct?
