+* TEXT
+* ATTACHMENT

+* PRIVATE GROUPS
+* BLOGS
+* FORUMS
+* IMPORT RSS
+* INTRODUCTIONS However, this is not strictly speaking necessary as all messages are treated the same - so if one type gets uploaded it means that all of them will. (Most recent mention of that in the testing channel in MM, on 19/09/22)
+
+The expected results are defined here 
+[Mailbox scenarios](https://code.briarproject.org/briar/briar/-/wikis/Mailbox-Scenarios)
+
+Scenarios:
+
+When X has a mailbox, but Y doesn't yet know about X's mailbox:
+
+* X will upload messages and acks for Y to X's mailbox
+* X will check X's mailbox for messages and acks uploaded by Y
+* Y won't upload anything to X's mailbox, or download anything from it, as Y doesn't yet know about X's mailbox
+* Communication via X's mailbox won't work in either direction
+* This problem will resolve itself when Y receives X's update informing Y about X's mailbox, which will happen the next time X and Y are online at the same time
+
+### Scenario 2: X has a mailbox that Y doesn't know about
+
+In this scenario, X and Y become contacts and then Y goes offline. While Y is offline, X links a mailbox (M). Y doesn't know about X's mailbox, because no connection has happened between X and Y since X linked the mailbox.
+
+While Y is offline, X writes a message to Y. X's message is uploaded to X's mailbox (one tick). Then X goes offline and Y comes back online. Y doesn't download X's message from X's mailbox because Y doesn't know about the mailbox yet.
+
+While X is offline, Y writes a message to X. Y's message is not uploaded to X's mailbox (clock icon), because Y doesn't know about the mailbox yet. Then X comes back online.
+
+When X and Y are online at the same time, both messages are sent and acked (two ticks).

+* While keeping Y online, bring X back online
+* Expectation: X is shown as online in Y's contact list and vice versa (after a delay of up to 2 minutes for X and Y to connect to each other)
+* Expectation: X's message appears in Y's conversation screen
