[exim] quite router

Hi there,


assume we have this router with working SQL:

virtual_blackhole:
driver = redirect
no_verify
domains = +local_domains
condition = ${lookup mysql{ ... is the address in the database at all
?.... }}
data = ${lookup mysql{ SELECT ':blackhole:' }}
allow_fail
allow_defer
group = mail
check_ancestor
no_more
directory_transport = address_directory
reply_transport = address_reply

Problem:

Is there a way to have a router which does the same AND does not really
produce a log messages about it ?
i.e. using a different transport or different driver ( drop maybe ) ?

best regards,

Marius Schwarz
