It could also be that the entire ISP's mail system was too full or too busy, from time to time. Or there was a networking problem between your ISP and the list. If your ISP uses greylisting, it rejects initial postings expecting the sending server to try again, later. Some senders will take the initial rejection and never try again. Some will try again later, but the "later" could be minutes, hours, or days later. If the ISP uses really crap greylisting, it might reject the resend, too. There's other anti-spam techniques that can backfire, too. If they don't like the look of the mail (mail not addressed "to" one of their users, as list mail isn't; the same message being received by many of their users; mail coming from lists, etc.). Some spam filtering is less-than well thought out. -- (This box runs FC5, my others run FC4 & FC6, in case that's important to the thread.) Don't send private replies to my address, the mailbox is ignored. I read messages from the public lists.
