Default mailman setting?

[optize]

So, it seems there's a default mailman setting for all of my cPanel installs. If you send to:

[email protected], it thinks it's a mailing list and will tell you you're not allowed to post there as you're not a member.

This becomes a problem due to spam, forged headers, etc.

However, I can't seem to configure the "default" mailman configuration. Does anyone else have this problem? Does sending a fake email to [email protected] reply back with a "you are not a subscriber" message and does anyone know how I can modify this default mailing list?

It's the same across many cPanel servers of ours, not a standalone issue.

I'm not sure I understand, the message that is returned to user clearly states its been rejected.

You are not allowed to post to this mailing list, and your message has
been automatically rejected. If you think that your messages are
being rejected in error, contact the mailing list owner at
[email protected]

Explain that to TrendMicro who had blacklisted our IPs because of this. They informed us that our servers are being used as bounce spam from mailman.

If you forge the From headers, send a spam message to [email protected], it will bounce and provide the spam to the new person.

I can't find any way to configure that default mailman account to turn off non-member bounces.

Hmm, not sure how helpful I can be there. Have you tried posting to the Mailman list?
