This is true, and I actually do this to an extent. But it has problems. For one thing, the transport layer doesn't have as much information available -- it's nice to be able to score based on other e-mails in the thread. For example, if the thread was started by Eric Raymond, then the thread can be marked down as not that interesting (and sorted to the bottom of the thread list). Then if "[OT]" starts appearing in the thread subject, the chances of anything relevant being said are probably low enough that it's not even worth reading the e-mail. So you need support for "who started the thread" and "what's the subject line" and the MTA Doesn't Do threads. Cameron Simpson wrote: > Depends how nice the scoring rule syntax is.

Usually (in Mutt), scoring takes place using information the mail client has to know anyway (name, subject, etc) to display the e-mail. If you really do want to scan the whole mail for scoring purposes, then yes that is better done at mail delivery time. (For example, I scan list mail to identify posts that are HTML-only, and put that information in X-Label, which Mutt will use for scoring purposes).

In my experience, the quirks of the particular mail program are likely to be there anyway, and will affect the way you can use scores, especially if the mail program isn't designed for scoring. You don't get much MUA-independence by moving scores to fixed headers. James. -- E-mail: james@ | [Bradford Cathedral] took 194 years to complete.
