sendmail.mc is the right place.
 
as for the setting not becoming active, probably there were sendmail
processes active.
 


Best,

Since the standard sendmail is not running, where do I put


LOCAL_DOMAIN(`smtp.johnnystork.ca')dnl 


in /etc/mail/sendmail.mc and rebuild sendmail.cf?

Or somewhere else? Putting it in /etc/mail/sendmail.mc, rebuilding and
restarting the MailScanner service did not appear to make any difference

btw: How/why does the hostname and internal ip of the laptop sending the
message also show up? (johnny-lt.johnnystork.ca) 



Not being a windows weenie I can't be sure but sounds like 
computer_name + domain_name on laptop. 



  (reason: 554 <unknown[207.216.240.22]>: Client host rejected: rDNS/DNS

This guy is more anal that me...(and I didn't think thats possible) 

He will be blocking hundreds of thousands of hosted domains worldwide. 
Enforce forward looking and enforce PTR, BUT there should never ever be any
full double match checking for reasons just mentioned, it's his problem, not
yours. 

His mailer is completely broken.. He is trying to read an earleir irrelevant
received line. The only one he should be concerend with is the connecting
one, in your case: (certain data munged deliberately) 

Received: from gateway.johnnystork.xxx (sputnik.xxxx.ca [207.xxx.xxx.xx]) 

Nowhere in THAT line does it reflect and internal address. 
If you gave real world DNS to gateway.xx.xx I'd maybe think ok its very far
remotely possible, but you haven't.
