Mutt and mail list issue

[W. D. McKinney]

I am subscriped to a mail list that will net let me post using my config
of Mutt 1.4i, which I suspect being a new user of mutt, might be a
common problem or one easily overcome. Maybe I could tossed some ideas.
They send back a notice saying they do not allow attachments. I am
wondering how to change the config for the mail list in question ?

Thanks-
