I'd enabled SMTP_AUTH in esmtpd and tested it worked for me. I only enabled one
line 127.0.0.1 allow,RELAYCLINET in my smtpaccess/default and run
makesmtpaccess. I think that there have only 2 messages the server will relay , one is from my
server by authenticated user, another is which to my locals and hosteddomains,
but why from secu...@moneybookers.com to yahoo.com enter my mail queue?
