Riposte solution
The server is listing supported URL authentication mechanisms (URLAUTH). This is advanced IMAP info and typically not directly used. No action required from your side; if you were attempting a URLAUTH that isn't supported, you would adjust accordingly. Riposte generally doesn't utilize this in basic operations.
