Bug 13042 – std.net.curl.SMTP doesn't send emails with libcurl-7.34.0 or newer

libcurl-7.34.0 was released on December 17 2013 [1]. Starting with this version, SMTP requires CURLOPT_UPLOAD option [2]. If CURLOPT_UPLOAD option is not set, libcurl emits VRFY command and no email is sent. [3] [1] http://curl.haxx.se/changes.html#7_34_0 [2] https://github.com/bagder/curl/commit/dac01ff6d788b20e5674e018a79f8a965b1e52bb#diff-65cc11e82be15630f137b0476644a46bL1668 [2] https://github.com/bagder/curl/commit/73a894170bce99ed71fcc764422f52a7cc4d3815 [2] http://curl.haxx.se/libcurl/c/smtp-tls.html [2] http://curl.haxx.se/libcurl/c/smtp-multi.html [2] http://curl.haxx.se/libcurl/c/smtp-ssl.html [2] http://curl.haxx.se/libcurl/c/smtp-mail.html [3] http://curl.haxx.se/libcurl/c/smtp-vrfy.html Fix: - Add 'p.curl.set(CurlOption.upload, 1L);' to std.net.curl.SMTP.initialize or - Add 'smtp.handle.set(CurlOption.upload, 1);' to user code. Example. auto smtp = SMTP("smtps://smtp.gmail.com"); smtp.handle.set(CurlOption.upload, 1); ... smtp.perform();

FYI, there's an ongoing discussion on the curl:bugs mailing list. http://curl.haxx.se/mail/tracker-2014-07/0030.html
