You can't. I take the point that this isn't well explained in section
40.2, and I'll improve it in the next edition. If you want to permit
mail to certain recipients as an exception, then you must use one of the
xxx_recipients options (e.g. sender_host_reject_recipients), so that
rejection happens at RCPT TO time, not when the host first connects.
Then you can use recipients_reject_except to permit mail to postmaster
to get through. I will also index "exceptions".

Depends what you mean by "I" and "store". Is "I" as system
administrator, or as an ordinary user? Is "store" "keep on the Exim
spool" or "deliver to some particular mailbox"? Either a system or a
user filter are probably the answers to this.

That is probably not possible exactly as you state it. What do you want
done with a message that has two addresses, one being one of your local
users, one being an attempt at at relay? With the current relay checking
facilities, the relay address is rejected at RCPT TO time, while the
local address is accepted and the delivery to that address proceeds. I
have made a note to think about ways of trapping rather than rejecting.

Depends on what protocol it is going to use when it logs in. Is it going
to be SMTP, or something else like UUCP? If it's SMTP, you can treat it
like any other remote host. Mail will sit on the Exim queue. (For
efficiency, setting a large retry time is a good idea.) When the host
logs in, it can issue an ETRN command to get anything waiting for it
delivered. See chapter 38 - "Intermittently connected hosts". (Actually,
I've just about said it all in this paragraph.)
I have added all these questions to my "stuff-for-use-when-writing-an-FAQ-
if-nobody-else-has-done-it-before-I-get-time" file.
