what do you exactly mean by "not used"? if you think it can be
"recycled", contact me offlist.

what you describe should work. you can check your map with 'psotmap -q

remove this. the default is good for everybody. the mail_name is used in
Received headers, and it's not very nice to make it harder to parse
these, given that it's already too hard than it should. people may
punish you by adding /WebTen ../ spamassassin rules.

oh no. don't mix transports and relay domains.

you'd be richer if you replace this with
.... Use of this server indicates that you agree to pay us a monthly fee
of 2000 USD, for a period of 12 months.
oh, and while I am in, my attorney recommends that I have no contact
with any organization which banners or disclaimers are not formally
validated. so you're gonna end up in my BL.
no, I'm not kidding. it's called a "risk minimization policy". and I
trust my attorney.

this is useless. the default is permit.

note that transport_maps is a "latency sensitive" map. you'd better have
your ldap respond as needed...
