While discussing Email , couple of terms keeping popping up. The terms are POP, IMAP, MAPI. So lets try and demystify these terms :
Here a Email Client would pull in the emails from a mailbox located on the Internet . So just like post office stores your email , the internet mail box would store your email till it is fetched.
2) IMAP :
In this , the email on the Internet mailbox is synced with the local email Client. The advantage in doing so is that you can access your email from virtually anywhere.
3) MAPI :
MAPI is a full groupware protocol, where is IMAP is only a Mail protocol.
So if you need Calendaring, Contact functionality, Tasks, server side mail filters, etc, then you need to use MAPI.
Needless to say , in terms of functionality , MAPI is the best . The best implementation of MAPI is when you use MS Outlook as a Client for MS Exchange . To know more about the features of MS Exchange , click here .
