Ruleset to NOT append to header. - Lotus Domino

[Hancock, Scott]

I have a vendor running The Lotus Domino Release 5.0.12.  Lotus is
rejecting my email because of the last two lines in the email header.

For example:

058  X-Morgan-MailScanner: Found to be clean
042  X-MailScanner-From: hancocknsd at morganco.com

If I delete these lines from the header, the mail is delivered.
Otherwise, my mail is rejected with 

554 Error writing message to safe storage; message could not be stored
to disk

In the conf file, I see I can make a ruleset.  

# Add this extra header to all mail as it is processed.
# This *must* include the colon ":" at the end.
# This can also be the filename of a ruleset.
Mail Header = %rules-dir%/writeheader.rules


Is this the proper syntax?
------------------------------------
# This next line gives an example of how you might enable this option
for
# a frequent customer of yours.

FromOrTo:          LotusServer.com        no

# Under no circumstances should this be changed to "yes".
FromOrTo:       default                 X-%org-name%-MailScanner:
-------------------------------------


Or should I tell this guy to straighten out his email system?  Any lotus
domino users here know the settings to fix this?


Thanks
