63 * Send a simple mail message using SquirrelMail's API.
64 *
65 * Until SquirrelMail is sufficiently redesigned, this
66 * function is a stand-in for a simple mail delivery
67 * call. Currently, it only sends plaintext messages
68 * (unless the caller uses the $message parameter).
69 *
70 * @param string $to The destination recipient.
71 * @param string $subject The message subject.
72 * @param string $body The message body.
73 * @param string $from The sender.
74 * @param string $cc The destination carbon-copy recipient.
75 * (OPTIONAL; default no Cc:)
76 * @param string $bcc The destination blind carbon-copy recipient.
77 * (OPTIONAL; default no Bcc:)
78 * @param object $message If the caller wants to construct a more
79 * complicated message themselves and pass
80 * it here, this function will take care
81 * of the rest - handing it over to SMTP
82 * or Sendmail. If this parameter is non-
83 * empty, all other parameters are ignored.
84 * (OPTIONAL: default is empty)
85 *
86 * @return array A two-element array, the first element being a
87 * boolean value indicating if the message was successfully
88 * sent or not, and the second element being the message's
89 * assigned Message-ID, if available (only available as of
90 * SquirrelMail 1.4.14 and 1.5.2)
