If I need a secure mailman list, is there another alternative?
You may want to give some thought to, and to then specify in a follow-up in this thread, what you mean by "secure" in this context.
For example, you might want security properties such as:
Every message sent to the list can be authenticated by its recipients.
Every message sent to the list is robustly encrypted to prevent its being readable by non-members.
For the property/ies above to be immune to rogue CAs.
Some combination of the above.
It may be helpful to ask yourself: what is your threat model?
Also, which key distribution mechanisms are available to you? (For instance: are the list members able to meet in person for key exchange?)
