The operational issues have already been addressed well in other posts. However the above statement is incorrect, and needs clarification. The items visible in your personal mail client (MUA) in the To:, Cc:, and Bcc: fields are usually called "addresses" or "addressees". These are different from "recipients", which are the addresses that the host-to-host mail program (MTA) sends to. Mailman "explodes" the list's *address* into a large number of *recipients*, and asks the MTA to deliver to that whole list of recipients, or to chunks of it as Mark explains elsewhere. You will in general never see the list of recipients of a post unless you look at the MTA's logs. By the way, there's nothing wrong with your understanding of plain English, in which "address" and "recipient" are pretty much the same. However, in technical discussion these words are often distinguished as above. > But in documentation is said that if this option is set to 0 it has > no limit. The limit you are running into here is not in Mailman, it is in the MTA. Mailman cannot tell the MTA what to do; it can only restrict itself to a small enough number that the MTA will cooperate with it. ------------------------------------------------------ Mailman-Users mailing list Mailman-Users@python.org http://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://wiki.list.org/x/AgA3 Security Policy: http://wiki.list.org/x/QIA9 Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ Unsubscribe: http://mail.python.org/mailman/options/mailman-users/archive%40jab.org
