OK, that's an awkward mixture to handle. I suspect you're going to have to manually spot Sieve filters and handle them separately. I assume you're working with file= rather than data= in your redirect router? So, starting with a filename, construct an expansion to identify by using ${readfile } and ${if match }. Use that in condition= in a redirect router immediately before your existing one. Tell your Sieve users to take off the trailing / from any explicit filenames. Use a transport which always appends a / and uses directory=.
Then raise a wishlist item for Exim's Sieve handling to support a means for configuring something other than "inbox". I'm unsure if a free choice is warranted, perhaps just a choice of "inbox/". -- Cheers, Jeremy -- ## subscription configuration (requires account): ## https://lists.exim.org/mailman3/postorius/lists/exim-users.lists.exim.org/ ## unsubscribe (doesn't require an account): ## exim-users-unsubscr...@lists.exim.org ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
