Email protection filters harmful or forged inbound messages and limits which mail may leave the organization automatically.
It is the filtering control on the mail path, narrower than the full program of identity, storage, and staff habits.
How it works
Inbound controls quarantine suspicious messages, mark external senders, and stop attachments or links that the organization has chosen not to allow.
Outbound controls reduce the chance that a compromised account sends large bursts or forwards sensitive files without review.
Filters make mistakes, so people need a fast way to release a legitimate message and a fast way to report one that got through.
A filter is not a reason to skip the second channel check on a payment change.
Concrete examples
- A payroll change request from an external lookalike address is quarantined before it reaches the inbox.
- An account that suddenly sends hundreds of messages is blocked from further outbound mail until the owner confirms it.
- A staff member releases a quarantined contract from a known partner after checking the request by phone.
Protective measures
- Quarantine inbound mail that fails your sender checks or carries content you have chosen to block.
- Limit automatic outbound bursts and require review when a mailbox suddenly sends far beyond its normal pattern.
- Give staff a supported way to release false quarantines and to report messages that should have been stopped.
- Keep payment changes on a second channel even when the message passed the filter.
