The server is the computer that stores your email. Enter fusion.mxrouting.net for both incoming and outgoing mail. Do not use your website address instead.
fusion.mxrouting.netFor incoming mail, choose IMAP
Incoming means messages you receive. Choose IMAP, enter port 993 and select SSL/TLS. These are the labels and numbers to choose in your app.
993SSL/TLSFor outgoing mail, choose SMTP
Outgoing means messages you send. Choose SMTP, enter port 465 and select SSL/TLS. If support asks you to use port 587 instead, choose STARTTLS with it.

Helpful notes
Keep in mind
IMAP is for mail
IMAP synchronizes mailbox folders. Calendar and contacts are separate services.
Which hostname should I use?
Copy the hostname supplied for this account. Do not guess mail.yourdomain.com or use an MX relay hostname; a public DNS record is not always the client-login endpoint.
Already have an account in another app?
Add the new mailbox separately. Do not remove existing accounts or local mail archives as part of basic setup.
