Hi,
I want to implement a POP3 email client to download messages from exchange server (using C#.Net).
After a POP3 connection is made, STAT command tells the count of messages available. Messages can be downloaded in that session using the sequence numbers. I want to know how POP3 service determines which messages are NEW for which client.
Suppose two clients (one mobile and one desktop application) connect to POP3 server. Mobile client downloads some messages. Now when desktop client connects to POP3 server, how will POP3 server determine which messages are new for this session (it should also return the messages which were downloaded by mobile client).
I looked a lot in documentation, but didn't found anything in this regard. Please help.
Regards,
Rajiv
