This can be taken care of by using an Alias Class which extends
EmailAddressList. The Alias class will contain one additional property
In fact the Alias is a Email client's burden and I am not sure if
mail API even needs it, since all aliases are expanded before sending

This can be handled by enum in C#. You need to add the Flags
Attribute to the enum and make sure the enum values have a single bit set.
Eg None=0, Seen=1, Answered=2, New=4...

Quite True. Its the burden of the Mail client.

It can be useful. Imagine an IMAP folder with some messages
in it. The client Gets A list of messages from the folder, marks
some of them as deleted and asks the API to save them. The methods
like ISExpunded can help in finding out if the message instance
has been deleted by the user and show appropriate label/image.
Only when you save the folder, is the message deleted from the
server. Now this saving can be automatic or user initiated.
For example pine deletes messages from the local spool only when
user exists and not when he marks them as deleted.
