Yes -- here's how I do this. Define this router:
# Mail for any local-part listed in /etc/exim/spamcheck_users is
# piped through my routespam script, which uses SpamAssassin to
# assess spamminess and routes messages accordingly.
spamcheck:
driver = accept
transport = spamcheck
local_parts = lsearch;/etc/exim/spamcheck_users
# Translated, this reads:
# if !(defined X-Spam-Flag) and
# !($received_protocol eq "spamc") and
# !($received_protocol ne "local") and
# !($sender_host_address ne 127.0.0.1) then:
# run this director
condition = "\
${if and { {!def:h_X-Spam-Flag:} \
{!eq {$received_protocol}{spamc}} \
{!eq {$received_protocol}{local}} \
{!eq {$sender_host_address}{127.0.0.1}} } \
{1}{0}}"
# No point sending mail back to the spammer, or a legit sender,
# if my routespam script dies.
errors_to = postmaster
retry_use_local_part
user = ${lookup{$local_part} lsearch {/etc/exim/spamcheck_users} {$value}}
group = mail
The corresponding transport:
spamcheck:
driver = pipe
command = "/etc/exim/routespam $sender_address $local_part@$domain"
delivery_date_add
envelope_to_add
log_output
path = "/usr/bin:/usr/sbin:/bin:/usr/local/bin"
return_output
return_path_add
