ejabberd-mod-message-log 0.2021.11.25~dfsg0-1 (amd64 binary) in ubuntu kinetic

 This module writes a line for each sent or received message to a log file.
 Each line mentions the sender's JID and the recipient's JID, and also the
 message type (e.g., "normal", "chat", or "groupchat"). Carbon copies are
 marked as such.
