Restricting access to Exchange Distribution list

[Nikumba]

We have a distribution list in Exchange 2010 for the IT Support team, however other people in the business are using it to send in support requests, which we do not want as we have a dedicated email for that.

I know I can restrict the access to send to the distribution list via the EMS however this will then stop our external IT support companies from emailing the same group.

Anyone know the best way to set it so only IT Support users can email IT Support distribution group and also receive email from external users?

Cheers

Add a contact for your externals, add them to a group. Block access to the dizzy list except for the group?

If we do that, then when we send to IT Support our external supplies will also get the email
