hi fred,
thanks for your response
i have an acl_smtp_helo ACL :
accept hosts = :
accept hosts = +relay_from_hosts
drop condition = ${if match{$sender_helo_name}{MY_IP}{yes}{no} }
message = "Dropped spammer pretending to be us"
drop condition = ${if match{$sender_helo_name}{^[0-9]\.[0-9]\.[0-9]\.[0-9]}
{yes}{no} }
message = "Dropped IP-only or IP-starting helo"
accept
i tested it with telnet, sending a helo/ehlo with the servers IP address or
any IP address drops the connection.
but at hosts without a resolved hostname even sending "ehlo" without any
arguments causes error 502 instead of error 501 Syntactically invalid EHLO
argument(s)
thanks
roman
