(I suppose you may be able to optimize that away for users that don't
have any content-dependent filters turned on, or if the user has an
"absolute" test (= "this is unwanted, no question" when it trips)
enabled that the mail fails before the content shows up.

will want such mail not dropped on the floor, but rather put in some
kind of "spam folder", in which case you _do_ need to store it
semi-permanently.

Oh, for heaven's sakes.

First off, if the E-mail is stored at the recipient end (where it makes sense 
to 
keep it, and process it, since that's where the bulk of the processing and 
storage resources are), disk space is currently going for US$0.35 to US$0.50 a 
gigabyte (even if you mirror it, doubling those prices still give you a 
(mirrored!) gigabyte for less than the price of a single typical daily 
newspaper).  Give the recipient the option to provide disk space, and store 
messages, or not provide disk space, and don't.  Simple.

Typical spam messages (once you strip the HTML garbage out of them) tend to be 
1K-5K bytes long.  So even if they were all 5K, you're talking about storing 
something like 200,000 spam E-mail messages (for however long the user bothers 
to keep them before they finally purge them, either actively or by simple 
timeout) for about ONE DOLLAR.

So what's with all this crap about it being so onerous to "accept and store" 
this stuff?

As for TEMPORARY E-mail storage (say at a POP3 server), mind you that it is the 
ISPs themselves who create that monster by trying to discourage users from 
setting up their own POP3 servers (which in fact is extremely simple to do, if 
you have a machine which is online and running essentially all the time).

But even if you don't have a fulltime POP3 server, it's fairly trivial to have 
a 
small background process running (as I do here) which empties POP3 mailboxes 
every minute or two.  There's really no point to agonize over the storage 
involved in handling this stuff, especially at the ISP end of things.

The only time my mailboxes get CLOSE to overflowing is if I'm away from home 
for 
an extended period, AND something happens here at home that takes my systems 
down until I get back.  So, exceptionally, I *might* use a lot of disk space 
(briefly) but then again, it's pretty rare for me under normal circumstances to 
have more than a couple of E-mails, total, in my Inboxes at any given time.

But then too, it's TRULY difficult for me to feel terribly sympathetic to an 
ISP 
who charges $80 a month for high-speed connectivity and then grouses about 
devoting even $0.25 (total, not per month) for 250Mb (peak!) of mirrored disk 
space at a POP3 server to hold that customer's mail.  And THAT is for those 
relatively enlightened ISPs that offer (just recently) 250Mb of Inbox space... 
compared to REALLY cheapo skinflints (like Comcast, but let's not name names) 
who (last I remember hearing) were still limiting their customers to a miserly 
10Mb of Inbox space each (about a penny's worth of hard drive space...).

Yeah, I'll tell you, I *really* feel sorry for them.

NOT!

Let's get real here, guys.  The amount of disk space it takes to store this 
stuff, compared to what people pay for these services, simply isn't a big deal 
(and, like bandwidth, it's becoming cheaper all the time).  And if we push the 
message storage to the user end (where it probably ought to be) then it's 
basically NO (storage, anyhow) skin off the ISP's nose at all.
