[exim] exim still accepting email after 550 from acl_check_h…

Hi all,

I have this simple setup:

acl_smtp_helo = acl_check_helo

begin acl

acl_check_helo:

   deny  message       = Your host did not present HELO/EHLO greeting.
         log_message   = SPAM remote host did not present HELO/EHLO 
greeting.
         condition     = ${if def:sender_helo_name {false}{true}}

   deny  message       = WE DON'T RELAY
         log_message   = SPAM remote host has blacklisted HELO.
         condition     = 
${lookup{$sender_helo_name}lsearch{/etc/exim/reject/helo}{yes}{no}}

accept

It works as expected, except that if I insist after the first 550 error,
the message still goes through...

Here's the session:
# telnet mail.asesoft.ro 25

How can I overcome this ?
