Properties

BounceAddress
BounceAddress

The bounced email address when a bounced email is recognized.

top
BounceData
BounceData
· string, read-only

The raw body of the bounced mail.

top
BounceType
BounceType
· integer, read-only

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.
9. Unsubscribe request.
10. Virus email notification.

13. Address Change Notification Messages.
14. Success DSN indicating that the message was successfully relayed.
15. Abuse/fraud feedback report.

DebugLogFilePath
DebugLogFilePath
· string

If set to a file path, causes each Chilkat method or property call to automatically append it's LastErrorText to the specified log file. The information is appended such that if a hang or crash occurs, it is possible to see the context in which the problem occurred, as well as a history of all Chilkat calls up to the point of the problem. The VerboseLogging property can be set to provide more detailed information.

This property is typically used for debugging the rare cases where a Chilkat method call hangs or generates an exception that halts program execution (i.e. crashes). A hang or crash should generally never happen. The typical causes of a hang are:

  1. a timeout related property was set to 0 to explicitly indicate that an infinite timeout is desired,
  2. the hang is actually a hang within an event callback (i.e. it is a hang within the application code), or
  3. there is an internal problem (bug) in the Chilkat code that causes the hang.

top
LastErrorHtml
LastErrorHtml
· string, read-only

Provides information in HTML format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.

top
LastErrorText
LastErrorText
· string, read-only

Provides information in plain-text format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.

top
LastErrorXml
LastErrorXml
· string, read-only

Provides information in XML format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.

top
LastMethodSuccess
LastMethodSuccess
· boolean
Introduced in version 9.5.0.52

Indicate whether the last method call succeeded or failed. A value of true indicates success, a value of false indicates failure. This property is automatically set for method calls. It is not modified by property accesses. The property is automatically set to indicate success for the following types of method calls:

  • Any method that returns a string.
  • Any method returning a Chilkat object, binary bytes, or a date/time.
  • Any method returning a standard boolean status value where success = true and failure = false.
  • Any method returning an integer where failure is defined by a return value less than zero.

Note: Methods that do not fit the above requirements will always set this property equal to true. For example, a method that returns no value (such as a "void" in C++) will technically always succeed.

top
VerboseLogging
VerboseLogging
· boolean

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
var status = ExamineEmail(email);
· Returns Boolean (true for success, false for failure).
· emailbool

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.

top
ExamineEml
var status = ExamineEml(emlFilename);
· Returns Boolean (true for success, false for failure).
· emlFilename String

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.

top
ExamineMime
var status = ExamineMime(mimeText);
· Returns Boolean (true for success, false for failure).
· mimeText String

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.

top
SaveLastError
var status = SaveLastError(path);
· Returns Boolean (true for success, false for failure).
· path String

Saves the last-error information (the contents of LastErrorXml) to an XML formatted file.

Returns true for success, false for failure.

top
UnlockComponent
var status = UnlockComponent(unlockCode);
· Returns Boolean (true for success, false for failure).
· unlockCode String

Unlocks the component. This must be called once at the beginning of your program to unlock the component. A purchased unlock code is provided when the Bounce component is licensed.

A purchased unlock code for the bounce component/library will included the substring "BOUNCE", or can be a Bundle unlock code.

Returns true for success, false for failure.
