Chat markers (XEP-0333) specification states that markers SHOULD be archived. This is already happening in one to one conversations in the personal archives but not in Group Chats. This module hooks the muc-message-is-historic event to customize the
mod_muc_mam behavior and have the chat markers archived.
First copy the module to the prosody plugins directory.
Then add “muc_mam_markers” to your
modules\_enabled list in your MUC component’s definition.
No configuration options are available.
