I have a filter (external program) that accepts a message on stdin, adds
some headers and produces the modified message on stdout (similar to the
way SpamAssassin works). Currently I have a transport filter set up to
handle this like:
iceni_transport:
driver = pipe
batch_max = 1000
use_bsmtp
command = /usr/sbin/exim -oMr iceni-scanned -bS
transport_filter = /usr/bin/mailfilterc $message_id $local_part
user = exim
log_output = true
This quite happilly accepts the mail and re-injects the modified message
into exim. The problem is that the re-injected message is treated as an
entirely new message - it gets a new message ID so it's not possible to
track a message on it's journey through the mail server by just grepping
the logs for it's message ID.
Is there any way to pipe a message through an external command, and then
continue on to process the message that's produced on the command's
stdout as if it were the same message rather than having to re-transmit
the command's output as an entirely new message?
