the RBL reject message text is very customizable. postfix.org UCE page
default_rbl_reply
The default reply template that is used when an SMTP client request is
blocked by a
reject_rbl or reject_rhsbl restriction. The reply template is subjected to
exactly one
level of $name macro substitution as described below. The
smtpd_expansion_filter
configuration parameter specifies the set of characters that are allowed in
$name macro
expansions. Characters outside the allowed set are replaced by "_".
Default:
default_rbl_reply = $rbl_code Service unavailable; $rbl_class [$rbl_what]
blocked using $rbl_domain${rbl_reason?; $rbl_reason}
