Get the Size of a POP3 Message by UIDL

See more POP3 Examples

Demonstrates the Chilkat MailMan.GetSizeByUidl method, which returns the size, in bytes, of the email on the POP3 server identified by a UIDL. The size includes the full message content, including attachments, and the method returns -1 on error. This example looks up a message's size by its UIDL.

// Important: Don't forget to include the call to System.loadLibrary
// as shown at the bottom of this code sample.

    CkMailMan mailman = new CkMailMan();

    int sizeBytes = mailman.GetSizeByUidl("0000000123abcdef");
    Log.i(TAG, "Message size (bytes): " + String.valueOf(sizeBytes));

    //  Note: Explicitly connecting/authenticating is optional.  Chilkat MailMan automatically
    //  connects and authenticates -- using the property settings above -- whenever a server
    //  operation requires it.  Calling the explicit connect/authenticate methods can still be
    //  helpful to determine whether a failure occurs while connecting or while authenticating.
