Xamarin - Email Application with Groups

This is a standard email application with Groups maintained by a server. Please read, to demonstrate you have read this, please include in the title "READING IS GOOD". EMAILS: This feature should include standard features of an email application with the ability to; read, write, send, reply, and receive/select messages. On the device there will be a (securely) stored and modifiable list of server connection information with the ability to select a default/active server. These server-list-items will work with standard email server protocols; smtp, pop, and imap. The inputs of To, CC, or BCC should give the user the ability to enter single or multiple email addresses and/or **a group list** identified by name. Obviously the only thing making this *special* is that we maintain the Group List of emails. GROUPS: There will be a list temporarily stored on the device. The list will be a key value pair will exist in a grouping called "EmailListItem"; consisting of a "name" with a semicolon(;) list of email addresses. This list will be provided by a server and in JSON format utilizing an HTTPS connection. JSON samples will be provided. The user will be able to add and edit lists. Upon submission validate all emails in the list. JSON samples will be provided. LOGIN: Prompt a user for credentials when starting app. Include a checkbox for auto-login and save credentials securely on device if the option is selected. JSON samples will be provided. Store the "VerificationCode" for later use. Include the ability to log off. RESPONSE FAILURES: Case 1, Specific fail; obtain new "VerificationCode" (max 3 attempts), then log out if fail. Case 2, Generic fail; display the "Message" to the user To demonstrate you have ACTUALLY read this, add "TO END" to the title. I hope to be working with you soon.
