What are the email header tags X-Abuse-Info used for and are they important

I've just received an email off someone with this in the email header i.e.

X-Abuse-Info:Sent using Newsapp, www.Newsapp.co.uk, support@Destnet.co.uk
X-Abuse-Info:Sent by info@xxx.com

I'm looking to send newsletter campaigns out myself, and was wondering if i should use these also? i.e. what are these used for?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

They're very likely to have been added by an anti-spam system. You should not need to manually add those to the header unless you've identified a specific need for them.

This was adding by the mta - sending the email.

Any ideas what purpose this would serve?
Chris DentPowerShell DeveloperCommented:

They're normally there to allow an Administrator, or support company (depending on the scenario), to identify why a message was (or wasn't) captured by a particular anti-spam system.

Many MTAs add their own information to a message header for this kind of thing. For example, SpamAssassin adds the following fields to the header:

X-Spam-Checker-Version: SpamAssassin 3.2.5 (2008-06-10) on someserver.domain.com
X-Spam-Level: **
X-Spam-Status: No, score=2.3 required=5.0 tests=MISSING_SUBJECT autolearn=disabled version=3.2.5

And probably a few more I didn't notice. It's generally not something to be too troubled by :)
