Gets the status of whether the failure is permanent (the client should not retry later) or transient (the client may retry later).

Namespace: MailBee.SmtpMail
Assembly: MailBee.NET (in MailBee.NET.dll) Version: 11.2.0 build 590 for .NET 4.5
bool IsTransientError { get; }

Property Value

Type: Boolean
true if the failure is transient, and the client may try again at a later time; false if the client should not try to send the same command with the same parameters later.

Transient errors correspond to 4xx status code, while permanent errors - to 5xx.

Typical case of a transient error is "Server is busy, try later". "Account does not exist" is a typical example of a permanent error. "Account is over quota" can be both permanent or transient error, depending on the mail server implementation.
