Properties
BounceAddress
The bounced email address when a bounced email is recognized.
topBounceData
The raw body of the bounced mail.
topBounceType
A number representing the type of bounce that was recognized.
A value of 0 indicates "No Bounce". Other values are:
1. Hard Bounce. The email could not be delivered and BounceAddress contains the failed email address.
2. Soft Bounce. A temporary condition exists causing the email delivery to fail. The BounceAddress property contains the failed email address.
3. General Bounced Mail, cannot determine if it is hard or soft, and the email address is not available.
4. General Bounced Mail, cannot determine if it is hard or soft, but an email address is available.
5. Mail Block. A bounce occured because the sender was blocked.
6. Auto-Reply/Out-of-Office email.
7. Transient message, such as "Delivery Status / No Action Required".
8. Subscribe request.

15. Abuse/fraud feedback report.
DebugLogFilePath
Procedure Set ComDebugLogFilePath String value
If set to a file path, this property logs the LastErrorText of each Chilkat method or property call to the specified file. This logging helps identify the context and history of Chilkat calls leading up to any crash or hang, aiding in debugging.
Enabling the VerboseLogging property provides more detailed information. This property is mainly used for debugging rare instances where a Chilkat method call causes a hang or crash, which should generally not happen.
Possible causes of hangs include:
- A timeout property set to 0, indicating an infinite timeout.
- A hang occurring within an event callback in the application code.
- An internal bug in the Chilkat code causing the hang.
LastBinaryResult
This property is mainly used in SQL Server stored procedures to retrieve binary data from the last method call that returned binary data. It is only accessible if Chilkat.Global.KeepBinaryResult is set to True. This feature allows for the retrieval of large varbinary results in an SQL Server environment, which has restrictions on returning large data via method calls, though temp tables can handle binary properties.
topLastErrorHtml
Provides HTML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.
topLastErrorText
Provides plain text information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.
LastErrorXml
Provides XML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.
topLastMethodSuccess
Procedure Set ComLastMethodSuccess Boolean value
Indicates the success or failure of the most recent method call: True means success, False means failure. This property remains unchanged by property setters or getters. This method is present to address challenges in checking for null or Nothing returns in certain programming languages.
topLastStringResult
In SQL Server stored procedures, this property holds the string return value of the most recent method call that returns a string. It is accessible only when Chilkat.Global.KeepStringResult is set to TRUE. SQL Server has limitations on string lengths returned from methods and properties, but temp tables can be used to access large strings.
LastStringResultLen
The length, in characters, of the string contained in the LastStringResult property.
topVerboseLogging
Procedure Set ComVerboseLogging Boolean value
If set to True, then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. The default value is False. Verbose logging should only be used for debugging. The potentially large quantity of logged information may adversely affect peformance.

Methods
ExamineEmail
Examines an email and sets the properties (BounceType, BounceAddress, BounceData) according to how the email is classified. This feature can only be used if Chilkat Mail is downloaded and installed, and it also requires Chilkat Mail to be licensed in addition to Chilkat Bounce.
Returns True for success, False for failure.
topExamineEml
Examines an email from a .eml file and sets the properties (BounceType, BounceAddress, BounceData) according to how the email is classified.
Returns True for success, False for failure.
topExamineMime
Examines an email represented as raw MIME text and sets the properties (BounceType, BounceAddress, BounceData) according to how the email is classified. The return value is 1 for a successful classification, or 0 for a failure.
Returns True for success, False for failure.
