Hola hacia tiempo que no publicaba nada en el blog jejeje y he dejado varios proyecto atrasados una disculpa a todo los seguidores pero hemos estado muy ocupado prometo que en las siguientes semanas habra mejores cosa
Pues bien para todos aquellos que esten configurando un servidor de correos y tenga serios problemas con el SMTP aqui les dejo una lista con los numeros de error esto es particularmente util a la hora de quere resolver nuestros problemas al saber cual es el error podemos ahorrarnos muchos dolores de cabeza y malos ratos
Error codes for the digits are listed here:
- 1: The server has accepted the command, but does not yet take action. A confirmation message is required. Currently, this is not used.
- 2: The server has completed the task successfully.
- 3: The server has understood the request, but requires further information to complete it.
- 4: The server has encountered a temporary failure. If the command is repeated without any change, it might be completed. This is hardly ever used by mail servers.
- 5: The server has encountered an error.
Errors codes for the second digit are:
- 0: A syntax error has occurred.
- 1: Indicates a informational reply, for example to a HELP request.
- 2: Refers to the connection status.
- 3 and 4 are unspecified.
- 5: Refers to the status of the mail system as a whole and the mail server in particular.
- 6: This digit refers to the status of the mail server.
Error codes list more specific errors as follows:
- 211 A system status message.
- 214 A help message for a human reader follows.
- 220 Service ready.
- 221 Service closing.
- 250 Requested action taken and completed. The best message of them all.
- 251 The recipient is not local to the server, but it will accept and forward the message.
- 252 The recipient cannot be VRFYed, but the server accepts the message and attempts delivery.
- 354 Start message input and end with <CRLF>.<CRLF>. This indicates that the server is ready to accept the message itself.
- 421 The service is not available and the connection will be closed.
- 422 The recipient has exceeded their mailbox limit. It could also be that the delivery directory on the Virtual server has exceeded its limit.
- 431 Not enough disk space on the delivery server. Microsoft say this NDR maybe reported as out-of-memory error.
- 432 Classic temporary problem, the Administrator has frozen the queue.
- 441 Intermittent network connection. The server has not yet responded. Classic temporary problem. If it persists, you will also a 5.4.x status code error.
- 442 The server started to deliver the message but then the connection was broken.
- 446 Too many hops. Most likely, the message is looping.
- 447 Problem with a timeout. Check receiving server connectors.
- 449 A DNS problem. Check your smart host setting on the SMTP connector. For example, check correct SMTP format. Also, use square brackets in the IP address [197.89.1.4] You can get this same NDR error if you have been deleting routing groups.
- 450 The requested command failed because the user’s mailbox was unavailable.
- 451 The command has been aborted due to a server error. Not your fault.
- 452 The command has been aborted because the server has insufficient system storage.
- 465 Multi-language situation. Your server does not have the correct language code page installed.
- 500 The server could not recognize the command due to a syntax error.
- 501 A syntax error was encountered in command arguments.
- 502 This command is not implemented.
- 503 The server has encountered a bad sequence of commands.
- 504 A command parameter is not implemented.
- 51x Problem with email address.
- 510 Often seen with contacts. Check the recipient address.
- 511 Another problem with the recipient address. Maybe an Outlook client replied to a message while offline.
- 512 SMTP; 550 Host unknown. An error is triggered when the host name can’t be found. For example, when trying to send an email to bob@ nonexistantdomain.com.
- 513 Another problem with contacts. Address field maybe empty. Check the address information.
- 514 Two objects have the same address, which confuses the categorizer.
- 515 Destination mailbox address invalid.
- 516 Mailbox may have moved.
- 517 Problem with senders mail attribute, check properties sheet in ADUC.
- 52x NDR caused by a problem with the large size of the email.
- 521 The message is too large. Else it could be a permissions problem. Check the recipient’s mailbox.
- 522 The recipient has exceeded their mailbox limit.
- 523 Recipient cannot receive messages this big. Server or connector limit exceeded.
- 524 Most likely, a distribution list or group is trying to send an email. Check where the expansion server is situated.
- 530 Problem with MTA, maybe someone has been editing the registry to disable the MTA / Store driver.
- 531 Mail system full.
- 532 System not accepting network messages.
- 533 Remote server has insufficient disk space to hold email.
- 534 Message too big.
- 535 Multiple Virtual Servers are using the same IP address and port. Email probably looping.
- 540 DNS Problem. There is no DNS server that can resolve this email address.
- 541 No answer from host.
- 542 Bad connection.
- 543 Routing server failure. No available route.
- 544 Cannot find the next hop.
- 546 Tricky looping problem, a contact has the same email address as an Active Directory user. One user is probably using an Alternate Recipient with the same email address as a contact.
- 547 Delivery time-out. Message is taking too long to be delivered.
- 548 Bad recipient policy.
- 550 The requested command failed because the user’s mailbox was unavailable (for example because it was not found, or because the command was rejected for policy reasons). Underlying SMTP 500 error. Our server tried ehlo, the recipient’s server did not understand and returned a 550 or 500 error.
- 551 The recipient is not local to the server. The server then gives a forward address to try.
- 552 The action was aborted due to exceeded storage allocation. Possibly the disk holding the operating system is full. Or could be a syntax error if you are executing SMTP from a telnet shell.
- 553 The command was aborted because the mailbox name is invalid. Could also be More than 5,000 recipients specified.
- 554 The transaction failed.
- 555 Wrong protocol version.
- 563 More than 250 attachments.
- 571 Permissions problem. For some reason the sender is not allowed to email this account. Perhaps an anonymous user is trying to send mail to a distribution list.
- 572 Distribution list cannot expand and so is unable to deliver its messages.
- 573 Internal server error, IP address related.
- 574 Extra security features not supported.
- 575 Cryptographic failure. Try a plain message with encryption.
- 576 Certificate problem, encryption level maybe to high.
- 577 Message integrity problem.
