Email and SMS bounces

 

EMAIL
 Code  Bounce name  Blacklist  Description
 0 Unknown/Undefined  NO
 1 Bad destination mailbox address  Permanent The specified email address does not exist. This means that the portion on the left of the @ is invalid.
 2 Bad destination system address  Temporary The domain specified in the email address is unable to accept emails.
 3 Bad destination mailbox address syntax  Temporary A syntactic problem has been detected by the receiving domain.
 4 Recipient Block Policy  Temporary The receiving user has created (only at the level of his own mailbox) a personal filter that blocks the address or domain sender of the email.
 5 Bad sender’s mailbox address syntax  NO The sender address was syntactically invalid.
 6 Bad sender’s system address  NO The sender domain is unable to accept reply emails.
 7 Other or undefined mailbox status  NO The mailbox was not able to accept emails.
 8 Mailbox disabled, not accepting messages  Temporary The mailbox exists but is not accepting messages. This may be a temporary or permanent error.
 9 Mailbox full  Temporary The user’s mailbox is full because its maximum capacity has been reached. You can clear it by deleting messages.
 10 Message length exceeds administrative limit  Temporary An administrative limit in the message size has been exceeded. This error occurs when the size allowed by the recipient’s box is smaller than the generic system limit.
 11 Reputation block  NO Message rejected due to reputation problems of the sender IP address or domain, caused for example by its presence in public blacklists or blocks by antispam systems, of the email providers that return this type of bounce. A problem of this type is resolved as soon as the IP or domain is unblocked or de-listed, so this type of bounce does not cause the email address to be blacklisted.
 12 No answer from host  NO The outbound connection attempt was not accepted either because the system was busy or because it was incapacitated.
 13 Bad connection  NO The outgoing connection was established but was unable to process the message, either because it went into time out or because of poor connection quality.
 14 Routing server failure  NO The system was unable to forward the message due to unavailable directory servers (e.g., inability to connect to DNS server).
 15 Unable to route  Temporary The system cannot find the correct path to the destination server. Sometimes it may also depend on the non-existence of the domain.
 16 Routing loop detected  NO Mail servers check if the same message passes through them more than once and after the umpteenth time (at the discretion of the postmaster as always) they decide that the message will never reach its destination and send it back notifying the rejection.
 17 Delivery time expired  NO Our system, in case of unreachability of the receiving mail server (without receiving specific rejection) performs multiple retries. If after 48 hours it is still not able to deliver the message it is considered failed and categorized as bounce. (the cause may be a server temporarily down or a domain with no MX records)
 18 Other or undefined protocol status  NO An error occurred in the message transmission protocol
 19 Invalid command  NO An out-of-sequence or unsupported protocol command was entered.
 20 Syntax error  NO A protocol command was entered that cannot be interpreted because the syntax is incorrect or it was not recognized.
 21 Delivery not authorized, message refused  NO The sender is not allowed to send to the specified recipient. The cause could be a blockage in the per-host or per-recipient spam filter.
 22 Relaying Denied  NO In a pass through the various servers, one of them could not deliver the email. The message is rejected by the server, it could be due to the sender being recognized as invalid or unacceptable
 23 Service not available – access denied  NO Typically caused by incorrect or old email addresses; when trying to deliver mail to a server that is intended only to send mail and not to receive it. Sometimes used as a response when mail is rejected as spam.
 24 Message considered to be spam  NO The message is considered spam
