It is quite a low bandwidth operation (probably less than 1K bytes) to poll > a POP server for email It's not the bandwidth - it's the fact that there are these annoying things called "timeouts". For *each* server that isn't reachable, you get to wait a minute or so - suddenly those 150 checks are taking quite some time. And the queuing theory of 150 sites with intermittent connectivity doing a push to your POP server is different than what you see when you try to do 150 pulls....

If your confirmation mail is being sniffed, you have *BIGGER* issues. And if you have bigger issues, I suggest using the *proper* tools for the job. See RFCs 2362-2364 and 3156.

There's a difference - I'm not proposing a new scheme of doing things that involves a change to 500 million users. So I submit to you that if this idea is too hard to use with the current version of Outlook, it is a *non starter* as a practical matter. > 50, even 5000, is not statistically bulk on internet scale.

Only problem is that many spammers are *already* only dropping 40-50 copies of a note at a site at a time, specifically to work around that - then the rest of the spamming recipients at your site get a different version with a different From: line and a different source IP address. I submit to you that if you didn't realize this was happening, you may not be qualified to be suggesting proposals to counter it.... (Hint - if spammers weren't doing this, it would be trivial to block them, and we'd not be HAVING this discussion, right? ;) > >It's ironic that you're proposing this on a push-based mailing list provided by > >an organization that is probably not in a position to provide POP accounts for > >the 30,000 or so recipients of the the list. > No. As I said above, they would only need to provide one POP account for this mailing list. And as I pointed out, you'll need to create 30,000, because one account doesn't allow you to keep track of who has already seen what messages. And no, you're *NOT* allowed to just say "everybody can fetch all the UIDLs and we'll just tag them with the subscriber ID" - go read and *UNDERSTAND* section 6.2 of RFC2298 in order to understand why. You might also want to go re-read the ASRG mailing list archives, your proposal (and variants thereof) has been kicked down the beach like a dead whale multiple times already.
