postscreen: 550 5.5.1 Protocol error

2011-10-18 Thread Jeetu 

Hi,

Im using postfix 2.8.5 with postscreen.
Im constantly getting this error message

Oct 18 08:02:10 inbound-us1 postfix/postscreen[12189]: NOQUEUE: reject: 
RCPT from [x.x.x.x]:64730: 550 5.5.1 Protocol error;

Can someone explain me whats wrong in my postscreen configuration ?

My postconf is
...
postscreen_access_list = permit_mynetworks,
hash:/etc/postfix/clients_access-postscreen

postscreen_blacklist_action = enforce
postscreen_client_connection_count_limit = 100
postscreen_dnsbl_action = enforce
postscreen_dnsbl_reply_map = texthash:/etc/postfix/dnsbl_reply
postscreen_dnsbl_sites = zen.mail.com
postscreen_greet_action = enforce
postscreen_helo_required = $smtpd_helo_required
postscreen_reject_footer = $smtpd_reject_footer
...

Nothing. The sending client doesn't properly speak SMTP.

The mail client makes errors in the SMTP protocol.

Grep the logfile for the client IP address, and it will show you
what kind of protocol error the client was making.
