6 * This file was at one time responsible for doing all deliveries, but this caused
7 * big problems on shared hosting systems, where the process might get killed by the
8 * hosting provider and nothing would get delivered.
9 * It now only delivers one message under certain cases, and invokes a queued
10 * delivery mechanism (include/deliver.php) to deliver individual contacts at
11 * controlled intervals.
12 * This has a much better chance of surviving random processes getting killed
13 * by the hosting provider.
14 * A lot of this code is duplicated in include/deliver.php until we have time to go back
15 * and re-structure the delivery procedure based on the obstacles that have been thrown at
16 * us by hosting providers.
