The current supported flags are CURLULFLAG_ANSWERED, which sets the Answered flag for IMAP uploads, CURLULFLAG_DELETED, which sets the Deleted flag for IMAP uploads, CURLULFLAG_DRAFT, which sets the Draft flag for IMAP uploads, CURLULFLAG_FLAGGED, which sets the Flagged flag for IMAP uploads, and CURLULFLAG_SEEN, which sets the Seen flag for IMAP uploads.

DEFAULT
A bitmask with only the CURLULFLAG_SEEN flag set.

PROTOCOLS
This functionality affects imap and imaps

EXAMPLE
static size_t read_cb(char *ptr, size_t size, size_t nmemb, void *userdata)
{
  FILE *src = userdata;
  /* copy as much data as possible into the 'ptr' buffer, but no more than
     'size' * 'nmemb' bytes */
  size_t retcode = fread(ptr, size, nmemb, src);
  return retcode;
}
int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    FILE *src = fopen("local-file", "r");
    curl_off_t fsize = 9876; /* set this to the size of the input file */
    /* we want to use our own read function */
    curl_easy_setopt(curl, CURLOPT_READFUNCTION, read_cb);
    /* enable uploading */
    curl_easy_setopt(curl, CURLOPT_UPLOAD, 1L);
    /* specify target */
    curl_easy_setopt(curl, CURLOPT_URL, "imap://example.com:993/mailbox");
    /* provide username */
    curl_easy_setopt(curl, CURLOPT_USERNAME, "user@example.com");
    /* provide password */
    curl_easy_setopt(curl, CURLOPT_PASSWORD, "password");
    /* specify that uploaded mail should be considered flagged */
    curl_easy_setopt(curl, CURLOPT_UPLOAD_FLAGS, CURLULFLAG_FLAGGED);
    /* now specify which pointer to pass to our callback */
    curl_easy_setopt(curl, CURLOPT_READDATA, src);
    /* Set the size of the file to upload */
    curl_easy_setopt(curl, CURLOPT_INFILESIZE_LARGE, (curl_off_t)fsize);
    /* perform the upload */
    curl_easy_perform(curl);
  }
}
