It's one of the rule actions. You can test a message and ignore it.
I used it to leave messages of a particular size on the server and
not download them. I then handled them on the server with a
different client.
Okay, I see now. I just tested using a rule in OE with the "do not
download" action clause. The problem I see with using that rule is that
your mailbox will fill up with messages that exceed the user-specified
size threshold and eventually your account will go dead because all of
its disk quota gets consumed (unless you periodically use the webmail
interface to check your mailbox). Say you have a 10MB disk quota for
your mailbox, you get e-mails that total over 10MB, and now every
subsequent incoming e-mail gets rejected with a bounce-back NDR
(non-delivery report) e-mail sent to the sender. You don't have a clue
that your mailbox's disk quota got all used up and then wonder why you
get no new e-mails while all your sender's wonder why they can't reach
you via e-mail anymore.
Since you cannot see the pending message in your mailbox in OE if you
use the "do not download" action in a rule that triggers on a message,
and if you do not periodically use the webmail interface to check your
Inbox on the server, and since you never see an item show up in OE's
Inbox to alert you that there are messages using up your mailbox quota,
then using the "do not download" action in a rule is hazardous. Since
you'll never see the big messages in your account waiting to get
downloaded, why not just use the "delete from server" action? You
aren't going to see the message anyway and deleting it (instead of
hiding it) prevents the possibility of rendering your mailbox dead
because all its disk quota got consumed.
As you said, you had to handle big e-mails (that were not download and
thus never listed in OE) using a different e-mail client, but that
assumes you actually checked your mailbox periodically with that other
client because you wouldn't know it was there waiting in your mailbox
with OE and when using the "do not download" action in a rule that
triggered on that big message.
In Outlook, you can configure to only download headers. You still get
the headers so the e-mail will get listed in the message list pane, but
you'll then have to mark the message for download and then pull all the
download-marked messages.
