Block it in a RCPT ACL but still route it normally.
Aliases handle the externally visible value, you route it normally to
the "real" user, but the real user can't be directly sent to if that
address is explicitly rejected at SMTP time.
Spec section 39 on ACLs, 39.20 on ACL conditions.
acl_smtp_rcpt = acl_check_rcpt
#[...]
begin acl
acl_check_rcpt:
#[...]
deny message = No such user
domains = +local_domains
local_parts = lsearch;MAILCONFDIR/reject_lhs_remote
#[...]
I use lsearch there because you can then put a custom message in and
make the value of "message =" be a ${lookup...} result, with an
appropriate default.
Then normal routing lets the mail be delivered to the user.
