Delivery TIPS

It is simple if you can prepare different files as necessary. For example, prepare

recipients.A
recipients.B
recipients.C

for the corresponding conditions A B C. Set up the following hook:

if (condition A matched) {
   $config->set('recipient_maps', "recipients.A");
}
elsif (condition B matched) {
   $config->set('recipient_maps', "recipients.B");
}
elsif (condition C matched) {
   $config->set('recipient_maps', "recipients.C");
}
