Below are the settings to use for email applications (Outlook, Thunderbird, Mac Mail, Smartphones):
POP/IMAP Account
Incoming server name: plesk.easy-hosting.co.nz
Incoming Port: leave the default setting (110 for POP, 143 for IMAP, 995 for POPSSL, or 993 for IMAPSSL).
TLS or SSL: Yes.
Username: your full e-mail address (including @yourdomain).
Password: provide the password you defined when creating the mailbox.
SMTP Account
Outgoing (SMTP) server name: plesk.easy-hosting.co.nz
Outgoing Port : 465 (with SSL) or 587 (with STARTTLS).
TLS or SSL : Yes.
SMTP Authentication : Yes, using the same settings as for the POP / IMAP account.
Some applications like Mac Mail may try to force the use of SSL. For compatibility and ease of use it is generally best to use STARTTLS (port 587) for the Outgoing server settings.
Smartphones will work with the same settings as listed above.
