append

Sends a APPEND command to append the message to the end of the mailbox. The optional flags argument is an array of flags to initially passing to the new message. The optional date_time argument specifies the creation time to assign to the new message; it defaults to the current time. For example:

imap.append("inbox", <<EOF.gsub(/\n/, "\r\n"), [:Seen], Time.now)
Subject: hello
From: shugo@ruby-lang.org
To: shugo@ruby-lang.org

hello world
EOF

A Net::IMAP::NoResponseError is raised if the mailbox does not exist (it is not created automatically), or if the flags, date_time, or message arguments contain errors.
