You can add up to 40 recipients.
Note: Avoid using many peer connections, if possible. The default delivery queue buffer for each
peer (
Max Queue Length) is 50 MB. Based on the default setting, to enable 20 peers,
20 * 50 MB = 1 GB of process memory for delivery buffers is required. If you use 40 peers, 2 GB of
process memory is required, exceeding the 32-bit process memory limit.If you want to use that many peers, then you must reduce the default delivery queue memory to 25 MB, keeping the total queue memory usage to 1 GB.
