Um...please understand, I cannot stand OE. And I cannot speak to the
Windoze version of the thing, but I _have_ installed/configured the Macintosh
version (5.02), and it _can_ filter on arbitrary header fields.
Under the Tools menu, select Rules. Create a new rule, name it. Under the
pop-up, select either "Specific Header" and fill in the header field name, or
select "Any Header"; either way, fill in the contents of, say, the list's
List-ID: header field, and in the "Action" box, tell it what to do with the
message (move it, copy it, eat it, whatever). Make sure it's Enabled, and
close the Rule and then the Rules window.
Unlike Eudora (at least the old 3.1 I intentionally use to avoid HTML,
those "folders" it transfers things into, but it does enbolden the folder
I would _never_ recommend OE to anyone (I think it's clunky, stilted, and
has less features and more security risks than an email application from
1997), but in fairness, at least in the Macintosh version, it CAN filter on
arbitrary header fields.
