I sure have a lot of questions recently. I'd like to prevent an owner from adding 100k subscribers to a list. We prefer to handle this load with 10 lists of 10k each and trigger their delivery by staggered Prime= headers. Is there an exit I could write to catch this or has someone already figured out how to catch this? -- Cheerfulness is contagious, but don't wait to catch it from others. Be a "carrier".
