You continue to post problems with mail delivery that do not appear to
be dovecot related. You are also cross posting between the Postfix
forum and this one.
From what I can gleam from your posts, you have tried to make some
whole sale changes in the Postfix "main.cf" and now things are messed
up. Replace your custom main.cf with the default on. Restart Postfix
and see what transpires. Post the results on the Postfix forum where
they belong. Do not modify the main.cf with any of your custom
modifications until you have first tried it. You may also have to
revert to the default master.cf also.
