Problem solved!
Finally it's not related to dovecot but to a misconfiguration of my
ldap_table in postfix.
So when my auto-reply message was send to the original sender, postfix did
a ldap query that did not take the domain part into account.
My original ldap_table was:
server_host = ldap.example.com
serverport = 389
bind = no
version = 3
search_base = ou=People,dc=example,dc=com
query_filter = (mailLocalAddress=%u)
result_attribute = mailRoutingAddress
start_tls = yes
The solution was to modify my search base with %2 instead of example.
Now when postfix do a query with another domain name, there's no result
because the search base doesn't exist.
Destination is not considered as local and forwarded to my relay host.
Bellow the update version of my ldap_table:
server_host = ldap.example.com
serverport = 389
bind = no
version = 3
search_base = ou=People,dc=%2,dc=com
query_filter = (mailLocalAddress=%u)
result_attribute = mailRoutingAddress
start_tls = yes
