Subject: Re: [exim] rejecting messages for unknown virtual users

I'm still getting the same problem.

I took the existence check out of the router, so now it is :-

localuser:
driver = accept
domains = +local_domains
transport = local_delivery




and my local delivery transport is :-

local_delivery:
driver = appendfile
directory = ${perl {get_user_dir}{$local_part}{$domain}}
user = exim
file_must_exist
no_check_owner
maildir_format
mode = 0660
delivery_date_add
envelope_to_add
return_path_add
quota = ${lookup{$local_part@$domain}dbm{/etc/mail/quota.db}}




but mail for non-existant users is still remaining on the queue, with these messages :-

2005-01-20 10:37:16 1CoPjW-0006zD-Pb == fred@??? R=localuser T=local_delivery defer (-1): Expansion of "${perl {get_user_dir}{$local_part}{$domain}}" (file or directory name
+for local_delivery transport) failed: Perl subroutine "get_user_dir" returned undef to force failure
2005-01-20 10:37:16 End queue run: pid=16142


so is there something i can change in my local_delivery router so that it will fail immediately if there is no directory?

to answer the question posed by Fred Viles :-

"
That should work. But if you can change the pathname pattern to
"data/mail/mydomain.com/username" you can simplify your configuration
(and make it more readable IMHO):

require_files = /data/mail/$domain/$local_part
"



- I cant do that as the mail directories are on different /data_nn partitions (data_01 , data_02, data_03 etc).
