I have some users that I do not want to mail outside of my company. In the EMC i go to Organization config>hub transport>transport rules. In there I made a rule that limits certain people in a distribution list to not being able to email outside.
The text of the rule is as follows:
Apply rule to message
From a member of 'internal_emails@blahblah.com' (this is the distribution group)
and sent to users that are 'outside the organization'
Send 'this account is not authorized to send external emails' to sender with '5.7.1'
The rule works fine but here is the issue: The user (auditor) that is sending the email is sending it to another group called reports. On this group is the quality supervisor (she is not in the group that limits her to internal only) and she travels sometimes for training. When she does she like me to forward her company email to a gmail account she can access on her cell phone. So when i turn forwarding on for her, the auditor gets a bounce message and the email seems to go poof. It does not make it to her outlook inbox or the gmail one.
This issue only pops up when someone on the internal_emails list tries to email someone with an external forwarder.
Is there a way that I can make it to where these people can not email out unless they are emailing a forwarder?
