We are working with a transport rule and are wanting to setup a Group that can only e-mail themselves. So far we have
Apply rule to messages
from a member of "group a"
Send "This message was rejected" to sender with "5.7.1"
Except when any of the recipients in the To or Cc field is a member of
"group a".
this works, except, if the e-mail is sent to a member of group A and also sent to anyone else the e-mail is allowed through.
Can a rule be setup to split the e-mail and deliver the e-mail to the member of group a but bounce the message that was addressed to the recipient that is not a member of group a.
