[courier-users] XFilter causing duplicate mail when sending to LDAP

Hi!

I've written two modules that process mail using xfilter - one adds a =

standardized, templated message footer based on LDAP data, the other =

normalizes From headers contents (based on LDAP too).

The filters run fine, with one exception: when a message recipient is an =

alias (mailing list) from LDAP (objectclass: CourierMailAlias), all the =

recipients specified in the LDAP maildrop attribute receive not one, but =

three version of the message:
The original version, version processed by the first XFilter filter, and =

version processed by the second one.

The filters end processing exactly as advised in xfilter documentation:

--- SNIP ---
....
# Return 250, no more filters should be run on this copy.
return '050 OK'
--- SNIP ---

Any ideas what could cause this?

BTW, this happens both when I use the original =

courier-pythonfilters-0.22 version and a version patched to submit =

messages using the "local" transport (see my other post today).
