| 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) |
