You could mail patches as plain text attachments, if there are concerns about the clients mangling them. You could also try some easier plain-text clients instead of mutt. Claws mail is a simple GUI based one.

But projects like Git do inline patches. I wouldn’t have the guts to break a convention like that when trying to submit something to the mailing list.
