Math Email

As for email applications, all of them, including mobile, can be configured to use your Math account using these generic settings:

Incoming server:, type: IMAP, port: 993
Connection type/encryption: TLS
Username: your Math username
Password: for the username above
Outgoing/SMTP server:, port: 465, protocol: TLS; authenticate with Math username and password.
