Umm, yes, and outside of the special case where you're sending

It's store and forward--so I don't see the network glitches. On a
pull system I do.
It's a tradeoff, like most technical decisions. The automatic
polling frequency could be anything from every second to never.

It's a tradeoff that the email "sender" has no control over.
Right. Just like right now, I have no control over when someone will
receive this e-mail. They might poll never, or every five minutes.
The issue is not when. The issue is that I don't want every person
who knows someone at my mail server polling my mail server every five
minutes to see if there is something new. That doesn't scale.
It is controlled by the receiver, who will of course set the
polling frequency as high as they can, since the cost to *them* is
low.
Someone (possibly you) already mentioned this as a problem, and I
already pointed out how easy it is to do connection limiting. By IP
would probably
That doesn't limit the polls. It just means that instead of aborting
them with "no mail" I abort them with "come back later". And if they
are well behaved, maybe they'll listen to when I tell them to come
back. But remember, we're talking about my fetching email from a
friend here. You aren't going to tell me to come back in a
week--even though that might be how often I get email from my friend.
And I'm not going to set my poll to a week, because I'm not willing
to have email from my friend arrive a week late. So you are
guaranteed that network traffic will be hire than in the current
situation.
I'm sure that if the sender had to pay we'd see a lot less spam.
I'm also certain that if the sender had to do thirty back flips
before each email message we'd see less spam. That doesn't mean
that not requiring back flips is what's wrong with email.
Well, many ISPs feel that the fact that the cost of spam is shifted
to them rather than the sender *is* a big problem. Feel free to
argue it out with them.
Many ISP feel that the fact that they are reimbursed for the cost of
receiving email is a problem. Who pays that cost is a separate
issue. But I give up--there's no point in continuing this argument.
But my client sits there, for days on end, attempting to get that
email, because it doesn't know whether it's from a spammer or
from a flakey ISP.
If you set your timeout to days, yes. And who would do that?
Anyone who didn't want to lose email?
Tell me, what's your POP3 or IMAP timeout set to? What's your HTTP
timeout set to?
Didn't think so.
Wrong timeout. We're talking about delivering email. The correct
question is, "What's the default timeout currently for most email
servers before they give up trying to send email." The typical
answer is four days.

I'm not sure which upsets me more: that people are so unwilling to accept
responsibility for their own actions, or that they are so eager to regulate
everyone else's.
