[Exim] Exim4 & delivery to Cyrus21 mail folders :-(

[Jim Archer]

Thanks!  This note is a HUGE help!

I was able to get deliver to put the message into the proper sub folder 
with the -a switch, as you said.  So then, I decided to tackle LMTP.  For 
some reason, this configuration did not work at all, meaning mail never 
made it from Exim4 to Cyrus21:

local_delivery_cyrus:
   driver = smtp
   protocol = lmtp

The Cyrus log gave no indication that Exim4 (I use 4.3) ever contacted it 
at all.

But I was able to get this to work:

local_delivery_cyrus:
  driver = lmtp
  socket = /var/run/cyrus/socket/lmtp
  batch_max = 100

This setup moves mail from Exim to Cyrus nicely.

But now I am back to my mail folder issue.  I added the ACL "anyone p" to 
both user.jim and user.jim.SPAM, and I then I put the local_part_suffix in 
the router:

local_user_cyrus:
  driver = accept
  local_part_suffix = SPAM
  transport = local_delivery_cyrus

I also tried +SPAM.  In each case, the email ended up in my inbox.  The 
exception is if I add check_local_user to the router, in which case it 
rejects the mail with user unknown.

So I guess I am back to my original question of how do I put mail directly 
into a folder, but now I at least have the benefit of running the more 
efficient LMTP protocol.

Thanks again...

Jim
