Some larger consumer IM services appear to handle this type of a
situation by not allowing registrations of old user names for a long
time. They basically just mark accounts as "inactive" rather than
removing them completely. This seems like a reasonable approach.
The server should also respond to stanzas with an error so the sending
endpoint would know that the account no longer exists.
Also, a.com should be smart enough to know that it was trying to
unregister a user and track the unreachable error stanza it receives
back from the S2S service, queueing up the original stanza to send
There are many S2S issues like this in the wild today with XMPP but they
are getting worked out over time as all the products mature.
