[SLUG] Query regarding 'Bounce' message from Slug Chat

[elliott-brennan <mail@xxxxxxxxxxxxxxxxxxxxx>]

Hi All,

This likely has a simple answer, but it's not one 
that readily appears to me.

Almost, if not every time, I post to slug-chat, I 
get a message back saying:

"Your message to slug-chat awaits moderator approval"

and

"Your mail to 'slug-chat' with the subject

    Query regarding FOSS and NSW Department of 
Education

Is being held until the list moderator can review 
it for approval.

The reason it is being held:

    Message has a suspicious header"

Invariably my message is posted; however I'm 
curious as to what I can do to prevent his occurring.

Could someone be kind enough to explain this to me 
please?

Many thanks for any assistance provided.

Regards,

Patrick
