Subject: smtp_mail: Added support to MAIL FROM for the optional SIZE parameter
X-Git-Tag: upstream/7.37.1~3635
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7f304ab84f560c9ddcd3ed1887bb4aa99a90bd6a;p=platform%2Fupstream%2Fcurl.git

smtp_mail: Added support to MAIL FROM for the optional SIZE parameter

The size of the email can now be set via CURLOPT_INFILESIZE. This
allows the email to be rejected by the server, if supported, and the
maximum size has been configured on the server.
