What you’re seeing
- Senders get a bounce reading 'Delivery has failed to these recipients or groups' naming your distribution list.
- Mail to a group like info@ or sales@ works from inside the company but bounces for customers and vendors.
- Some staff members can email the group and others get rejected, with a note that they lack permission to send to it.
- The group's membership looks correct, and messages to individual members get through.
Common causes
Every environment is different, but these are the causes our engineers find most often:
- The group is set to accept messages only from authenticated (internal) senders, which blocks everyone outside the organization.
- Delivery management restricts sending to a specific list of people, and the sender is not on it.
- Message approval or moderation is enabled and the moderator is unavailable or the request expired.
- The group was recreated or migrated and its address no longer matches the address people are sending to.
- A size limit on the group is lower than the message being sent, such as a large attachment.
Why it matters
Shared addresses are often how customers, applicants and suppliers reach the business. When they bounce, quote requests, job applications and support tickets are rejected without anyone internally knowing. The sender usually gives up rather than trying another address, so the cost shows up as missed leads and unhappy customers rather than an obvious outage. Internal teams can also miss announcements if certain staff are blocked from posting.

Frequently asked questions
How long has this been bouncing?
It often starts when a group is created or changed, and message traces can usually show when rejections began. Our engineer can review that history so you know which senders may have been affected.
Will opening the group to outside senders invite spam?
It can increase it somewhat, which is why the right setting depends on how the group is used. We confirm what the group is for before changing who can send to it.
