It is possible to set storage of message receipts, and add other types to save:
sess-man/plugins-conf/amp/msg-store-offline-paths[s]=/message/received[urn:xmpp:receipts],/message/store-offline,-/message/do-not-store
The above setting in the init.properties file will do three things: - Messages with a <received> subelement of xmlns set to urn:xmpp:receipts will now be stored. - Messages with <store-offline> subelement will be stored without checking for associated xmlns. - Messages with <do-not-store> element will not be saved.
Any of these can be adjusted for your installation, remember that a '-' will stop storage of messages with the indicated property. Messages will be checked by these matchers and if any of them result in a positive they will override default settings. Matcher logic uses left to right ordering, in that matches on the first statement will ignore/override later listed matchers.
For example, if you wanted to store messages with <received> element, but not ones with <plain> element: THIS STATEMENT WILL NOT WORK
sess-man/plugins-conf/amp/msg-store-offline-paths[s]=/message/received,-/message/plain
As it will just store all messages with <receieved> subelement. The below statement will properly filter your results.
sess-man/plugins-conf/amp/msg-store-offline-paths[s]=-/message/plain,/message/received
