22 * A mail which has been completely downloaded will have no special headers,
23 * and its entry in the uidl file will end by 0 (POP3_TOTALLY_RECEIVED);
25 * A mail which has been partially downloaded will have some special headers,
26 * and its entry in the uidl file will first be 1 (POP3_PARTIALLY_RECEIVED);
27 * the special headers will be including "SC-Marked-For-Download" which can
29 * 0 (POP3_PARTIAL_DLOAD_UNKN) meaning that the user has not yet chosen to
30 * download the mail or let it be deleted - this header is absent until the
31 * user first chooses an action
32 * 1 (POP3_PARTIAL_DLOAD_DLOAD) meaning that the user wants to finish
33 * downloading the mail
34 * 2 (POP3_PARTIAL_DLOAD_DELE) meaning that the user does not want to finish
35 * downloading the mail
36 * When updating this header to POP3_PARTIAL_DLOAD_DLOAD, the uidl line of
37 * this mail will end with the mail's physical path, which Sylpheed will remove
38 * after having downloaded the complete mail. msg->partial_recv will equal
39 * 2 (POP3_MUST_COMPLETE_RECV).
40 * When updating this header to POP3_PARTIAL_DLOAD_DELE, the uidl line of
41 * this mail will be 0 (POP3_TOTALLY_RECEIVED), which will let Sylpheed delete
42 * this mail from the server as soon as the leave_time preference specifies.
