In case of an immediate error, it logs /* a warning (except EPIPE) with the client address and port, /* and returns a non-zero result (all errors including EPIPE). /* /* psc_send_reply() does a best effort to send the reply, but /* it won't block when the output is throttled by a hostile /* peer. /* /* PSC_SEND_REPLY() is a legacy wrapper for psc_send_reply(). /* It will eventually be replaced by its expansion. /* /* psc_send_socket() sends the specified socket to the real /* Postfix SMTP server. The socket is delivered in the background. /* This function must be called after all other session-related /* work is finished including postscreen cache updates. /* /* In case of an immediate error, psc_send_socket() sends a 421 /* reply to the remote SMTP client and closes the connection. /* If the 220- greeting was sent, sending 421 would be invalid; /* instead, the client is redirected to the dummy SMTP engine /* which sends the 421 reply at the first legitimate opportunity. /* LICENSE /* .ad
