+ * Send a simple mail message using SquirrelMail's API.
+ *
+ * Until SquirrelMail is sufficiently redesigned, this
+ * function is a stand-in for a simple mail delivery
+ * call. Currently, it only sends plaintext messages
+ * (unless the caller uses the $message parameter).
+ *
+ * @param string $to The destination recipient.
+ * @param string $subject The message subject.
+ * @param string $body The message body.
+ * @param string $from The sender.
+ * @param string $cc The destination carbon-copy recipient.
+ * (OPTIONAL; default no Cc:)
+ * @param string $bcc The destination blind carbon-copy recipient.
+ * (OPTIONAL; default no Bcc:)
+ * @param object $message If the caller wants to construct a more
+ * complicated message themselves and pass
+ * it here, this function will take care
+ * of the rest - handing it over to SMTP
+ * or Sendmail. If this parameter is non-
+ * empty, all other parameters are ignored.
+ * (OPTIONAL: default is empty)
+ *
+ * @return array A two-element array, the first element being a
+ * boolean value indicating if the message was successfully
+ * sent or not, and the second element being the message's
+ * assigned Message-ID, if available (only available as of
+ * SquirrelMail 1.4.14 and 1.5.2)
