@ -1649,6 +1649,12 @@ Pass a long to tell libcurl how to act on transfer decoding. If set to zero,
transfer decoding will be disabled, if set to 1 it is enabled
(default). libcurl does chunked transfer decoding by default unless this
option is set to zero. (added in 7.16.2)
.IP CURLOPT_EXPECT_100_TIMEOUT_MS
Pass a long to tell libcurl the number of milliseconds to wait for a server
response with the HTTP status 100 (Continue), 417 (Expectation Failed) or
similar after sending a HTTP request containing an Expect: 100-continue
header. If this times out before a response is received, the request body is
sent anyway. By default, libcurl waits 1000 milliseconds. (Added in 7.36.0)
.SH SMTP OPTIONS
.IP CURLOPT_MAIL_FROM
Pass a pointer to a zero terminated string as parameter. This should be used
