I found the problem. The script should listen like "while read line" ... conditions.

I was trying to capture the query in that /tmp/spawn file. I get empty lines. I don't think I get a correct query in 127.0.0.1:5555. It connects, gets the echo and closes. I will read more about tcp_table lookups since it appears I didn't understand it, probably not even the role of spawn. I'm trying to add a feature where IP pools can be used for outbound depending on the source domain (sender_dependent_default_transport_maps) and destination domains (transport_maps). I'm quite comfortable with bash and the queries should be forwarded to a local DNS where .localzones will alternate the IPs in each pool and outbound smtp. Is an idea I have to try. Thank you.

I suggest that you test it by hand first. $ telnet 127.0.0.1 5555 Then send it a query. > #!/bin/bash > echo "$@" >> /tmp/spawn > printf "220 spawn_test:\n" # was echo "220 spawn_test:" > exit 0 First, it is not a good idea to pass random filth from the Internet into shell commands. What happens when the expansion of "$@" starts with a '-' character? Second, spawning bash every time there is a query will severely limit the amount of email you can handle. The tcp_table requires a persistent server. Why do you need TCP table, and why are MySQL, SQLite or LDAP not sufficient? Wietse
