We're neophytes here, having just moved the list over from Yahoo, and appreciate the help offered here. I expect we'll (I'll) need some handholding for a while. Personally, my Unix is rusty; the last time I used much of it was 1995. This ><[log in to unmask]>: >Sorry, no mailbox here by that name. (#5.1.1) turned out to be a server burp at ptd.net. It was coincidental that it happened today. The flood of Yahoo errors was not. Here's how we handled it ------------------------ * We have 60 [log in to unmask] subscribers. We made a list of those who were already on NOMAIL, then put all Yahoo subscribers on NOMAIL. * Time passes. Another subscriber here (that would be Jane) told me that error messages were slowing down for her list. * We "query listname with nomail for *@yahoo.*" * We made a mailing list from the results, deleted the names that should stay on NOMAIL, and divvied up the list. (We are seven.) This leaves a managable number for each owner to contact. If we get a reply, we'll set the subscriber's account to MAIL; if not, it'll stay on NOMAIL. How Yahoo created this mess --------------------------- Yahoo has started charging $30 per year for "enhanced" mail services: POP3, mail forwarding to primary account, and the ability to read mail in a regular e-mail client instead of on their ad-laden screens. Today was the day that the charges took effect, so Yahoo dumped anyone who was using the "enhanced" services and hadn't paid for them. Boom, at once. Since our default is individual messages, we started getting a flood of bounce notices--one per super-unpaid Yahoo subscriber per each post to the list.
