I checked a few setting as explained. I have a stupid question and also
my results.
First of all it is not just comming from postini. It once in a while
wonders in from the outside. Not that I know how since all my mx records
points to postini. Just random junk I suspose.
One of your lookup tables is making you a partial open relay.
The usual suspects include:
- incorrect mynetworks
- firewall/NAT config that makes foreign connections appear as
local
- faulty relay_domains lookup
- faulty virtual_* lookup
- access table in smtpd_recipient_restrictions BEFORE
reject_unauth_destination.
- compromised user mail account.

Speculation is pointless. Postfix makes decisions based on
the config you give it, and logs all actions taken.
For more detailed logging, add a single -v to the
smtp ... smtpd
entry in master.cf, and post the unedited logging of unwanted
relaying, plus your CURRENT 'postconf -n'.
