The SmtpFailedRecipientsException type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | SmtpFailedRecipientsException() | Initializes an empty instance of the SmtpFailedRecipientsException class. |
![]() | SmtpFailedRecipientsException(String) | Initializes a new instance of the SmtpFailedRecipientsException class with the specified String. |
![]() | SmtpFailedRecipientsException(SerializationInfo, StreamingContext) | Initializes a new instance of the SmtpFailedRecipientsException class from the specified instances of the SerializationInfo and StreamingContext classes. |
![]() | SmtpFailedRecipientsException(String, Exception) | Initializes a new instance of the SmtpFailedRecipientsException class with the specified String and inner Exception. |
![]() | SmtpFailedRecipientsException(String, array<SmtpFailedRecipientException>) | Initializes a new instance of the SmtpFailedRecipientsException class with the specified String and array of type SmtpFailedRecipientException. |
| Name | Description | |
|---|---|---|
![]() | Data | Gets a collection of key/value pairs that provide additional user-defined information about the exception. (Inherited from Exception.) |
![]() | FailedRecipient | Indicates the e-mail address with delivery difficulties. (Inherited from SmtpFailedRecipientException.) |
![]() | HelpLink | Gets or sets a link to the help file associated with this exception. (Inherited from Exception.) |
![]() | HResult | Gets or sets HRESULT, a coded numerical value that is assigned to a specific exception. (Inherited from Exception.) |
![]() | InnerException | Gets the Exception instance that caused the current exception. (Inherited from Exception.) |
![]() | InnerExceptions | Gets one or more SmtpFailedRecipientExceptions that indicate the e-mail recipients with SMTP delivery errors. |
![]() | Message | Gets a message that describes the current exception. (Inherited from Exception.) |
![]() | Source | Gets or sets the name of the application or the object that causes the error. (Inherited from Exception.) |

![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() | GetObjectData | Infrastructure. Populates a SerializationInfo instance with the data that is needed to serialize the SmtpFailedRecipientsException. (Overrides SmtpFailedRecipientException::GetObjectData(SerializationInfo, StreamingContext).) |
![]() | GetType | Gets the runtime type of the current instance. (Inherited from Exception.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | ToString | Creates and returns a string representation of the current exception. (Inherited from Exception.) |
| Name | Description | |

![]() ![]() | ISerializable::GetObjectData | Infrastructure. Initializes a new instance of the SmtpFailedRecipientsException class from the specified SerializationInfo and StreamingContext instances. |
The InnerExceptions property contains the exceptions received while attempting to send e-mail. The e-mail might have been successfully delivered to some of the recipients.
The following code example resends an e-mail message that was not delivered because a mailbox was busy or unavailable.
static void RetryIfBusy( String^ server ) { MailAddress^ from = gcnew MailAddress( L"ben@contoso.com" ); MailAddress^ to = gcnew MailAddress( L"jane@contoso.com" ); MailMessage^ message = gcnew MailMessage( from,to ); // message.Subject = "Using the SmtpClient class."; message->Subject = L"Using the SmtpClient class."; message->Body = L"Using this feature, you can send an e-mail message from an application very easily."; // Add a carbon copy recipient. MailAddress^ copy = gcnew MailAddress( L"Notifications@contoso.com" ); message->CC->Add( copy ); SmtpClient^ client = gcnew SmtpClient( server ); // Include credentials if the server requires them. client->Credentials = dynamic_cast<ICredentialsByHost^>(CredentialCache::DefaultNetworkCredentials); Console::WriteLine( L"Sending an e-mail message to {0} using the SMTP host {1}.", to->Address, client->Host ); try { client->Send( message ); } catch ( SmtpFailedRecipientsException^ ex ) { for ( int i = 0; i < ex->InnerExceptions->Length; i++ ) { SmtpStatusCode status = ex->InnerExceptions[ i ]->StatusCode; if ( status == SmtpStatusCode::MailboxBusy || status == SmtpStatusCode::MailboxUnavailable ) { Console::WriteLine( L"Delivery failed - retrying in 5 seconds." ); System::Threading::Thread::Sleep( 5000 ); client->Send( message ); } else { Console::WriteLine( L"Failed to deliver message to {0}", ex->InnerExceptions[ i ] ); } } } catch ( Exception^ ex ) { Console::WriteLine(L"Exception caught in RetryIfBusy(): {0}", ex->ToString() ); } finally { client->~SmtpClient(); } }
