Your mail sending client is busted. You can debug this with tcpdump (capture to file, then examine the SMTP conversation with wireshark. Or you can have Postfix log the conversation with: # postconf debug_peer_level=1 debug_peer_list=x.x.x.x > postfix/smtpd[21089]: too many errors after RSET from unknown For safety reasons Postfix limits the number of RSET, NOOP, etc. commands. The counter is reset after the client sends an email message. In your case, no mail is sent. Wietse
