RackMail has put together the best help for setting up your devices that we can find and its specific for your email service and brand of device!
or if you just need settings:
IMAP / SMTP Settings
SSL On
| User | yourname@yourdomain.com | |
| Password | your specific email password | |
| Incoming mail server name: | secure.emailsrvr.com | Port: 993 |
| Outgoing mail server smtp: | secure.emailsrvr.com | Port: 465 or 587 |
Using POP
You can use POP instead of IMAP for incoming mail, however it is not recommended if you will be using multiple devices to check your mail.
The incoming settings for POP are the same as for IMAP, except the Port # is 995.
