We use the following rules in acl_check_rcpt, but I suspect they would work better in acl_check_helo

deny
condition = ${if and{{eq{$interface_port}{587}} {eq{$tls_cipher}{}} } }
message = All port 587 connections must use TLS

deny condition = ${if eq{$interface_port}{587}}
!authenticated = *
message = All port 587 connections must be Authenticated
