Hello! We have a unofficial email server for fans of Zorin OS, including mail clients that don't support SSL, and it supports POP3/IMAP/SMTP/XMPP and a web interface. Just go to https://zorinmail.org - create your account and then you can add it to your desired Zorin mail client.
Note: to be able to send outgoing Internet mail you need to register at Zorin City Email Service Subscription Landing Page - This is to prevent scammers from subscribing and using it to send spam. When checking out you can choose the "free" payment method if you don't want to pay.
It also provides a XMPP service so you can use Pidgin or PSi or other XMPP client to chat with other Zorin fans.
This service is free and always will be. Inbound mail is scanned both for spam and viruses. If you have any questions just PM me or send email to marisag@haikumail.online .
Looking forward to working with you!
