Hello, Yes, that's really embarrassing that the mailing list does not change the "reply-to" header in the mail sent to the list.
Ok, now I understand your problem better. I guess that for your needs, the create_graph_tables would need to be enhanced to handle graph direction better. Unfortunately, I won't have time to work in this, but you can still fill a bug report there http://bugzilla.maptools.org/query.cgi (use product CartoWeb, and put [pgdijkstra] in the bug title) if you want to keep an eye on it. If you can provide examples and a detailed description how you think it should behave, that's better.
