Spamming???
I have turned up the logging on my SMTP Service and i see a lot of this...
This is an SMTP protocol error log for virtual server ID 1, connection #45560. The remote host "216.159.242.70", responded to the SMTP command "rcpt" with "550 5.1.1 User unknown ". The full command sent was "RCPT TO:<saoyocxq@boelter-yates .com> ". This will probably cause the connection to fail.
Are people spamming through me?

Cause: Recipient Filtering had been enabled for "recipients not in the directory"
No one is spamming you :) atleast thats what I think.
If you really want to check try sending a mail to your self by telnet usung bogus email as sender.

Connection filtering is a real nice feature and you would be away from most of the blacklisted IP's that are known to all small and big BLOCKLISTING companies.

If you find too many of the above events being generated, its an indication that someone is trying to harvest your address book to get names and email address of all valid users in your organization.
