Post via email tags

Hi all

I am trying to configure posting via email to my site. I have the emails coming through fine. The subject is ok but the tags are not working properly. They dont get set as tags but just get included in the body of the post.

As an example I would send

Test
[tags testtag]

The above 2 lines are what show in the body of my post and there are no tags.

Any help would be appreciated as I am going mad trying to figure this out.

Thanks
Richard
