you are new to this list, so please accept some friendly advice (this is
to help you get the most out of this list):
- always provide full details: what happens, what you want, ... and
here, prefer clarity over anything else (people may understand terms
differently, so try to express your problem in a way as to maximize
understanding, "possibly at the expense of anything else" ;-p).
- show relevant postfix logs ("normal" logging. only show verbose
logging after you've been asked).
- show your config (at start, 'postconf -n' output. then if asked,
master.cf).
while it may be clear for you that "users should not send mail", this is
not clear to us. indeed, in almost all setups,
- anyone can send mail to your domains
- anyone can send mail anywhere using the sendmail command
- anyone can do anything using $random software. in short, there is no
evidence that your users are using postfix. said otherwise, nothing in
your mail tells us that users are posting via postfix. postfix logs are
needed.

what do you really mean here? sending mail and receiving mail (in the
sense: mail is delivered to their mailbox) and reading mail are three
(3) different things.
it may be easier for you to specify
- who should send mail (under what conditions)
- who should receive mail (under which conditions)
