this is the stage:
CentOS 7x64 in Vultr server with CyberPanel con SSL
In Outlook and more
POP3 email with SSL works Well (Receive and send)
IMAP email with SSL works Well (Receive and send)
POP3 email without SSL Does not work
IMAP email without SSL Doesn’t Work
SMTP email without SSL Doesn’t Work
CentOS 7x64 in Vultr server with Plesk con SSL
In Outlook and more
POP3 email with SSL works Well (Receive and send)
IMAP email with SSL works Well (Receive and send)
POP3 email without SSL works Well (Receive and send)
IMAP email without SSL works Well (Receive and send)
SMTP email without SSL works Well (Receive and send)
Why does Cyberpanel not work in outlook without SSL? and PLESK if it works with SSL and without SSL.
Is there any special configuration so I can work correctly, since I don’t want to leave cyberpanel and use Plesk for that problem 
thanks since now.
