Suspecting a mail routing issue, here is a summary of port assignments from various config files (full config files are in original post). Maybe this will allow someone to see a problem that I am missing.
Also, a bit of history may help... this server has been migrated from a functional installation running on Lenny. I inherited the Lenny server, installed the Jessie server from scratch, migrated the users, etc. across, installed new package versions and have been reconfiguring as needed for the newer versions. The port assignments below are the same as those used on the Lenny server, with one exception - the smtp-amavis content filter in main.cf on Lenny used port 10028, not 10024. I've tried both on Jessie and get the same non-functional results. It confounds me as to how the old server using 10028, which is the dkimproxy_out relay port, could have been working. But again, I've inherited this, and consequently am learning much on the fly. Anyway, hopefully this little summary will help someone to see something I can't.
