There's no such thing as chain mail, if I remember rightly, at least not in terms of item naming, though it appears on many models. If there is, it's medium armour and it's made by Leatherworkers. Armoursmiths make heavy armour exclusively, which is equivalent to plate in terms of looks.

The confusion arises, as far as I know, from the fact that many armour models have "chain mail" bits in them, and the presence of such items in other games.

Anyway, best I know is if you want medium armour go see (or make) a leatherworker (outfitter spec), and if you want heavy armour you'll need an armoursmith. Light, of course, is made by tailors.
