Step 2

  • Create a POP3 connection:

    BOOL Create(LPCSTR pszHostName, int nPort);

Step 3

  • Connect to the POP3 server:

    BOOL Connect(LPCSTR pszUser, LPCSTR pszPassword);

Step 4

  • Get status form server:

    BOOL GetStat(CString *strStat);

  • Get mail list from server:

    BOOL GetMailList(CStringList *strResult);

  • Get a mail header:

    BOOL GetMailHeader(int nMailIndex , CString *strMailHeader);

  • Get a mail sender:

    BOOL GetMailSender(int nMailIndex, CString *strSender);

  • Get a mail receiver:

    BOOL GetMailReceiver(int nMailIndex, CString *strReceiver);

    BOOL GetMail(int nMailIndex, LPCSTR tmpfilename);

  • Delete a mail:

    BOOL DeleteMail(int nMailIndex);

  • Reset the mail list:

    BOOL ResetMail();

  • Get last error:

    BOOL GetLastError(CString *msg);

  • Get timeout setting:

    BOOL GetTimeOut(DWORD *dwTimeOut);

  • Set timeout:

    BOOL SetTimeOut(DWORD dwTimeOut);

  • Get the buffer size of receive:

    BOOL GetReceiveBufSize(long *lSize);

  • Set the buffer size of receive:
