Hi, My config dovecot 2.2.13 Postfix 2.9.6 Debian wheezy When I send a message to my user test (siroco) postfix said unknown user But the user exist : doveadm user siroco : field value uid 3002 gid 2000 home /var/spool/dovecot/mail/s/siroco mail maildir:~/Maildir:LAYOUT=fs postmap -vq siroco ldap:/etc/postfix/ldap_virtual_aliases.cf return siroco 2 questions : postfix search with siroco or with siroco at citoyens2015.marche.be ? postmap must return siroco or siroco at citoyen2015.marche.be ? And I don't know if I set for alias_maps, virtual_mailbox_maps, virtual_alias_maps ?
