-5xx class - Server Error
-
This status code indicates that the

-
-
-
-| 500 |
-500 Internal Server Error
-
An internal server error has caused
-the server to abort your request. This is an error condition that may also
-indicate a misconfiguration with the web server. However, the most common
-reason for 500 server errors is when you try to execute a script that has
-syntax errors. |
-
-
-
-| 501 |
-501 Not Implemented
-
This code is generated by a webserver
-when the client requests a service that is not implemented on the server.
-Typically, not implemented codes are returned when a client attempts to
-POST data to a non-CGI (ie, the form action tag refers to a non-executable
-file). |
-
-
-
-| 502 |
-502 Bad Gateway
-
The server, when acting as a proxy,
-issues this response when it receives a bad response from an upstream or
-support server. |
-
-
-
-| 503 |
-503 Service Unavailable
-
The web server is too busy processing
-current requests to listen to a new client. This error represents a serious
-problem with the webserver (normally solved with a reboot). |
-
-
-
-| 504 |
-504 Gateway Timeout
-
Gateway timeouts are normally issued
-by proxy servers when an upstream or support server doesn't respond to
-a request in a timely fashion. |
-
-
-
-| 505 |
-505 HTTP Version Not Supported
-
The server issues this status code
-when a client tries to talk using an HTTP protocol that the server doesn't
-support or is configured to ignore. |

-
Your ISP mail server indicates that an email address does not exist or the mailbox is busy. It could be the network connection went down while sending, or it could also happen if the remote mail server does not want to accept mail from you for some reason i.e. (IP address, From address, Recipient, etc.) |

-453 Too many messages
-
Some mail servers have the option to reduce the number of concurrent connection and also the number of messages sent per connection. If you have a lot of messages queued up it could go over the max number of messages per connection. To see if this is the case you can try submitting only a few messages to that domain at a time and then keep increasing the number until you find the maximum number accepted by the server. |
