[MM3-users] Problem replying via Hyperkitty

Hello Everyone,

A few of my users read our mailing list through Hyperkitty. Whenever they reply through the web, their replies simply disappear. One example from today was logged as follows:

[pid: 2287|app: 0|req: 116007/153551] xxx.xx.xx.xx () {72 vars in 1992 bytes} [Thu Jun 30 11:26:16 2022] POST /archives/list/listname@domainname.org/message/46WUOPZITVMKJN4TXR6CP3WMFUEAVJKD/reply => generated 3213 bytes in 70 msecs (HTTP/1.1 200) 6 headers in 188 bytes (3 switches on core 0)

A couple of basic questions:

1. when a users replies in this manner, does their response go to the list or to the subscriber to whom they are replying?
2. what log files could I check to see what — if anything — happens to these emails?
3. Are there any settings that need to be set to make this work?

Thanks much. Any help will be appreciated.

Jeff
