import and filter mail using "Delivered-To" header

[VargaG]

We were trying to use mailpiler but quickly ran into the issue of the outside mailing lists. It would be great if we could import mail from the users mailboxes and somehow use the "Delivered-To" header for searches. Would this be difficult to implement? It would eliminate a lot of "who can see which e-mail" issues. It would also solve the mailing list membership issues (for example if a user was only temporarily member of a mailing list).

Try setting the following in piler.conf:

extra_to_field=Delivered-To:

I believe that it will fix the problem. If not, then send me a non sensitive email with full headers to my address (see piler -V output), and I'll check it.
