When a script sends a form it uses the current user as the sender and 
appends the server name on the end e.g. apache (at mark) ns3.mydomain.net

Sendmail then does a quick check on all messages that it sends to ensure 
that the sender is real and not spoofed.

So, check your form script to make sure it's setting the sender of the 
message as well as the recipient.  This isn't totally required but it's 
good practice and makes for a more professional e-mail too :-)

Ensure the sender e.g. query (at mark) example.com has a user or an alias to a 
user of query under the example.com site.

I hope that makes sense.
