Hello, I'm using postfix(2.4.5) and dovecot(1.0.5), and till now I have been using postfix deliver agent. Now I have tried to reconfigure postfix to use the dovecot LDA, but I'm getting some strange error:

Try this:

socket listen {

 master {
   path = /path/to/run/dovecot/auth-master
   mode = 0600
   user = your_dovecot_user_name
   group = your_dovecot_user_name
 }

 client {
   path = /path/to/postfix/private/auth
   mode = 0660
   user = your_postfix_user_name
   group = your_postfix_group_name
 }

}

protocol lda {

postmaster_address = postmaster@tld.com

mail_plugin_dir = /path/to/lib/dovecot/lda

sendmail_path = /usr/sbin/sendmail <-- this is the usual postfix
path to sendmail

auth_socket_path = /path/to/run/dovecot/auth-master

}
