Imail's list server is the most basic of list servers, missing key design points such as automatic bounce processing and double opt-in un/suscribe. Imail's queue processing, used by the list server, uses a single subdirectory, so having a few 10 or 100 thousands files in the queue is disaster. You should get a dedicated Mailing List Manager, MLM, and a infrastructure class Mail Transfer Agent, MTA. The easiest way to achieve volume and reliability is to split the total list over several machines, where parallelism gives both throughput and redundancy.
