Hi,
lately, I receive strange e-mails to users on a private lan. Below a
sample header:

Now my questions. How is this possible when thiam.ch doesn't even exist
in the internet? Do I have an uninvited guest on my Postfix mail server,
which is, by the way, behind a firewall and uses a private IP address?
Is there a HowTo explaining how to set up postfix with user password
etc? Maybe even over a secure connection?
Thx
Thiemo
