Hi folks,

I recently tried to upgrade my install of Exim 4.12 to 4.34 and hit a configuration problem I can't track down. Here is a summary of my config and an explanation of what no longer works. Any help appreciated.

I host several virtual-mail domains with a combination of:
Exim + Exim Filters
Courier-Imap/POP
Bogofilter
using Maildirs

I use a simple directory structure (the one expected by Courier-Imap) as the basis of my config. It is as follows:

For each domain I have a home directory of the form: /home/vmail/[domain name]
For each user I have a directory in the domain dir of the form: /home/vmail/[domain name]/[mailbox name]

In addition I, each domain may have an optional 'alias' file used by a router to perform forwards:
/home/vmail/[domain name]/alias

And each user may optionaly have a 'exim.filter' file used for Exim filter rules as such:
/home/vmail/[domain name]/[mailbox name]/exim.filter

My router chain functions as follows--

Router 0: Relay - if not for a local domain, do remote_smtp delivery (protected by ACLs so only relay's for local system)

Router 1: Bogofilter -- pipes all mail for local delivery domains to bogofilter for spam scanning. A header is added to indicate that the message has been scanned so that when it is piped back through Exim, this router is skipped.

Router 2: Filters -- all local delivery mail for which there is an actual mailbox directory AND an exim.filter file is passed to the redirect transport for filter processing.

Router 3: Accept -- all local delivery mail for which the local part does _not_ exist in the alias file is delivered locally

Router 4: Alias redirect -- all undelivered local mail gets processed by alias file

Under 4.12 this works fine.

Under 4.34, inbound mail is passed to Bogofilter, but when it is passed _back_ to Exim it goes directly to local delivery and is not processed for Filters or Aliases. Rolling back to 4.12 solved the problem.

I've included my Router and Transport definitions at the end of this message--any suggestions or pointers to what might be wrong greatly appreciated.

cheers,

Jeff
