I already have $final_bad_header_destiny = D_PASS.

I have virtual_transport = dovecot. I guess I need to look harder at the mysql
queries. Most mail gets delivered correctly it is only messages that amavisd
says have bad headers. I would think that if I had a problem with the dovecot
queries, I would have more problems getting mail delivered properly. Maybe I
need to ask about the "user unknown" problem on the dovecot list.

I will give that a try. It will take some time to determine if that helps.

Not really. If I turn off SOFTBOUNCE then the messages get bounced to the
postmaster which happens to be me. I turned SOFTBOUNCE on in the hope that
I would get more information, be able to correct the problem and deliver the
messages properly.
Thanks for the information.
