Hi Oliver,

Try these subtle enhancements to your transport - I use the same tools
but on RedHat:

[ snip ]
>       home_directory = "/tmp"
>       current_directory = "/tmp"
>       user = Debian-exim
>       group = Debian-exim
>       return_fail_output
>       message_prefix =
>       message_suffix =
>       log_output = true


I've always had the following in addition to the above:

     batch_max = 5
     return_path_add = false


This helps SA from getting bogged down - the batch_max -- under way too
heavy load, SA seems (to me!) to not always perform correctly. Adding a
lot of RAM could help - spamd is a memory pig. Taking a glance, I have
three spamd procs each using a SIZE 116meg and RSS 102meg. Oi veh.

Such a large batch condition will happen when you have an alias expanded
to a bucketload of final delivery addresses - ie a project/staff alias.
Adjust the value to your machinery power of course. You could also try
rearranging your routers so that SA is called *before* final alias
expansion, so that it's scanned only once.
