Change the default option for "Delivery Management" for groups in Exchange admin
When creating a distribution or security group, "delivery management" defaults to "Only senders inside my organization".
Considering that most companies do business with people outside of their organization, admins need to be able to change this.
If the admin forgets to specifically change this setting, many emails are lost and there's no notification of delivery failure to either the sender or the intended recipient. The emails are just... lost entirely.
This can result in lost vendors, lost clients, lost customers and lost business!
We need the ability to change the default option for delivery management to "Senders inside and outside of my organization"
Im completely with Jeff... :) I am one of those 'people like jeff' who thinks it should be a deliberate step every time.
With all due respect for Jeff's concern over spam, the original poster's point is the bigger problem in many cases. If a company is relying on difficulty in assigning members to distribution groups as a key security move, they have bigger problems. At the very least, please allow admins to change the default behavior, even if it starts as-is for people like Jeff.
Having a distribution list open to external senders by default is an incredibly shortsighted view if you have any concern about email security at all. All it takes is one malicious actor on the internet to find your DL open and you have exposed large numbers of users to phishing attacks. It's a real bonus for the bad guys. What's worse is if you have contacts in the DLs representing client emails. You've then managed to enable the bad guys to send malicious email to your clients too! Not really good business practice to spam your clients like that. The lists should default to closed and can be opened based upon an informed evaluation of the consequences.
good idea. this is an option we are missing right now
Excellent suggestion. I agree entirely and this is something which is easier to see in previous on premise versions of Exchange. The default should always be open to all senders, and not just inside your organisation
