Riposte solution
The client attempted to enable compression (DEFLATE) when it's already active. This is an IMAP protocol detail. Riposte, if using compression, will manage it. This alert means a duplicate compression request was ignored. No action needed — just ensure not to re-negotiate compression. Riposte won't normally let this happen in the first place.
