Features of message comparison:

Text of a mail message or post stored in Microsoft Outlook base may be in one of the following formats: HTML, RTF, plain text (see help for more details). When DER compares mail message texts, it gives preference to the Plain Text format. This format is chosen as the most versatile one. The RTF and HTML format are only used if a message or post cannot be presented in the Plain Text format. While comparing message or post texts, DER ignores spaces, hyphens and tab symbols since they carry no additional information.

When DER compares internet headers of message, it ignores the information about message service sites and the time of message transmission through those services. This is because the same message transmitted through different services will have different heading, but it won't contain any additional information.

One or more files can be attached to a mail message or post. DER compares both names and contents of attached files.

Any message has two important parameters: sending date and time and receiving date and time. Date and time of mail message receiving cannot be used as message comparing criterion, as one and the same message may received in different time. That's why only sending date and time are compared. With posts, the posting time is used for comparing.
