These should usually be resolved automatically, and you should receive a final bounce-back message if the message completely fails. You usually would not receive a bounce-back message for this type of error. If your message is going to be delayed more than 24 hours, then sometimes a "delivery has been delayed" soft bounce will be returned to you, to let you know that the delivery has yet to complete succesfully.

Join error 421 cannot connect to smtp server them; it only takes a minute: Sign up Server reading in data from client not working up vote 2 down vote favorite EDIT--I have included some test classes. Sadly with these test files, the server isn't writing any data to http://www.inmotionhosting.com/support/email/bounceback-errors/email-error-421 the files it receives from the client. Idk why either. It's the best I can give atm. edit again- Also, I noticed that while testing this, the test text files will be read in by the Client and printed in the terminal. But if I add new text to the test text files, it still reads in the old data. Maybe it's cause it's in an eclipse dir, idk. Server-http://pastebin.com/F7xzMdes SeverMultiCLient - http://pastebin.com/HQM7PyGj Client- http://pastebin.com/hBSLZsus The goal of this http://stackoverflow.com/questions/18094400/server-reading-in-data-from-client-not-working program is for the Client to write data to a file. There are 2 files that the clients writes. The client will then read in each line of the first file and send it to the server. The server will then write each line to its own file. This is repeated again for the second file. What's working? : The client writing all data to its files The client reading in each line KIND OF(some small issues) before sending to server The server is writing data (wrong data) The server IS writing data to the correct file What's not working?: The server is not writing the correct data to its files - This is the problem. It's repeating the same line over and over again EDIT: The real problem is that the String it keeps getting from the Client is the same over and over again. Files to Compare: The following 2 Links should match (EXCEPT the first line) Notice Sever has one extra line and repeated data Client's Mouse Coor http://pastebin.com/RnEGgBJm Server's Mouse Coor http://pastebin.com/cBqfLHnf The following 2 links contain the terminal sessions Each line the server READS in from the client. This is what's written to the Server's file, this should match the client's terminal session http://pastebin.com/A4xqWGiu Each line the client reads in from it's file right BEFORE sending to the server. The same variable that is sent, is printed to its terminal.
point of view of the network layer: connections, timeouts, buffers, and other similar topics are covered here. The information contained in this document is only applicable to Redis version 2.6 or greater. *How client connections are accepted Redis accepts clients connections on the configured listening TCP port and on the Unix socket http://redis.io/topics/clients if enabled. When a new client connection is accepted the following operations are performed: The client socket is put in non-blocking state since Redis uses multiplexing and non-blocking I/O. The TCP_NODELAY option is set in order to ensure that we don't have delays in our connection. A readable file event is created so that Redis is able to collect the client queries as soon as new data is available to be read on the socket. After the client is initialized, error 421 Redis checks if we are already at the limit of the number of clients that it is possible to handle simultaneously (this is configured using the maxclients configuration directive, see the next section of this document for further information). In case it can't accept the current client because the maximum number of clients was already accepted, Redis tries to send an error to the client in order to make it aware of this condition, and closes the connection immediately. The service not available error message will be able to reach the client even if the connection is closed immediately by Redis because the new socket output buffer is usually big enough to contain the error, so the kernel will handle the transmission of the error. *In what order clients are served The order is determined by a combination of the client socket file descriptor number and order in which the kernel reports events, so the order is to be considered as unspecified. However Redis does the following two things when serving clients: It only performs a single read() system call every time there is something new to read from the client socket, in order to ensure that if we have multiple clients connected, and a few are very demanding clients sending queries at an high rate, other clients are not penalized and will not experience a bad latency figure. However once new data is read from a client, all the queries contained in the current buffers are processed sequentially. This improves locality and does not need iterating a second time to see if there are clients that need some processing time. *Maximum number of clients In Redis 2.4 there was an hard-coded limit about the maximum number of clients that was possible to handle simultaneously. In Redis 2.6 this limit is dynamic: by default is set to 10000 clients, unless otherwise stated by the maxclients directive in Redis.conf. However Redis ch
