email bounced if sent to group of people   

this is odd, we have occasionally an issue where A user from external domain 
sends us an email and where his/her email is delivery to us as long email is 
send to 1 person, but as soon this A user from external domain sends email to 
a group of people he/she gets NDR, but only about our domain. Other words if 
there is 10 email addresses this email is send only those sent to our domain 
return NDR

any idea?

Can you post the NDR?  When you say a group of people, do you mean a 
Distribution List or mulitple addresses?

well, here is why this is happening very strange (see link) but at least we 
know there is nothing we can do until this is resolved by easydns and Bell. I 
originaly said "email send to group" because this is how it looks like as we 
were troubleshooting this but now we know it is random regardless how meny 
email addresses is included in TI or CC
