L4 looks to be sending "QUIT" and dropping connection, not allowing for the "221 2.0.0 Bye" reply, that ends up trying to flush. Apart from changing "smtpd_timeout" to lessen the time it takes flush to give up, are there any other options I could use?
L4 in that case is broken because if we talk about SMTP the server has to close the connection after client sending QUIT
