Re: --headers limit

[積丹尼 Dan Jacobson]

Yes, I am talking about -H headers: one line per message.

E.g., for a remote mailbox with a thousands of mails in it, if I just
want to see what the last 20, or first 20 messages' headers are, with
the minimum of data passing over the wire.

Yes, best would be just 20 lines of data passing over the wire.

But OK, each message needs 5 lines of header to make the one line we see
on our screens with -H.

So OK, 20 * 5 = 100 lines passing over the wire.
