Thank you for clearing that up 😀
The only thing I get from that links is per below
Then digging around on their Site
and finally this
1. What Settings you'll Need
When setting up your email on a device or mail client (e.g Outlook/MacMail), you'll need the login details for your email account and the server information to be able to gain access.
2. Username and Password Settings
These are the same for both incoming and outgoing servers
Username: Your ".myzen.co.uk" or your Zen username (zen123456@zen) email address
Email Address: Same as your username, unless you're using an alias on a "@zen.co.uk" email address
Password: This should be the password you set for the account, in the Zen Customer Portal
3. Incoming Mail Settings
Server Name: mailhost.zen.co.uk
Type: POP3
Port: 995 (110 if 995 doesn't work, but this is less secure)
Encryption Type: TLS/SSL
