I am configuring migrating from one server postfix with courier to a 
server with postfix and dovecot. I'm also trying to migrate the mailman 
who currently works in the postfix server I have the following 

myhostname = mail.dominio.com
mydomain = dominio.com
myorigin = $mydomain
mydestination = localhost, $myhostname
relayhost =
mynetworks =,,
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = all

# for mailman
owner_request_special = no
recipient_delimiter = +
alias_maps = hash:/var/lib/mailman/data/aliases

virtual_alias_maps = mysql:/etc/postfix/mysql-virtual_forwardings.cf, 
virtual_mailbox_domains = mysql:/etc/postfix/mysql-virtual_domains.cf
virtual_mailbox_maps = mysql:/etc/postfix/mysql-virtual_mailboxes.cf
virtual_transport = dovecot
virtual_mailbox_base = /mnt/maildir
virtual_uid_maps = static:1001
virtual_gid_maps = static:1001

I copied the directories of the mailman date, archives and lists the 
current server to the new facility and issued the following commands

# cd /var/lib/mailman
# bin/genaliases
# bin/withlist -a -l -r fix_url

with that lists the current server appear in the web interface and 
command execution "bin/list_lists" but when I try to send an email to 
the list in the logs of postfix and get a bounce message "user unknown"
