Convert a mailman archive to wordpress posts

Hello everyone,

The subject says it all.
I have a list of mailman archive list (text files) that i would like to arrange to wordpress posts and the answers emails for a given subject as comments, I will close my mailing list service and do not want to loose all the subject that were listed for years now.

I don’t know how to do that or if there is a plugin to do that, I saw that there is a wp-mailman plugin but this is not what I want to do.

Any idea ?

Thanks
