Block or unblock outgoing email

Open Spam AutoShield and choose the mail server whose policy you want to inspect. The master must be on for stored entries to take effect; see the illustrated Spam AutoShield guide.

Outgoing email identifies a local sending mailbox. This blank form has not added an entry. Select the image to enlarge it; use your browser's Back command to return.

1. Click Add entry and choose Block.
2. Set Entry type to Outgoing email and enter the complete local sending address.
3. Choose Apply to, review the servers, then click Add blocked entry.
4. Read every server’s result and refresh the intended list.

To remove the block, filter List and Type, find the exact value, and use Remove on the displayed server. Review its confirmation and result.

Investigate the compromised mailbox, reset its password and check the sending device or website before unblocking it. Review automatic outbound limits.

Command-line method

From a root terminal on the intended mail server, stop a local sender from sending mail:

cpfence --add-spam-autoshield-out-email [email protected]

After cleanup and verification, remove the block:

cpfence --del-spam-autoshield-out-email [email protected]

Replace the example with the intended complete local mailbox address. The commands update this server’s policy, not the WebUI’s Apply to selection. Read the result and refresh its outgoing-email block list.

Automatic outbound protection

Enable Outbound rate limits while Spam AutoShield is on, then tune SMTP hourly limit and Website hourly limit for normal traffic. Automatically added sending blocks stay until removed; see outbound limits.

Reset a compromised mailbox’s password and check its sending device or website before unblocking. Verify subsequent sending and watch for renewed abuse; removing the block does not repair the source of the spam.
