Bonjour à tous
J’ai un postfix installé sur une debian11 qui fonctionne correctement à l’exception des alias.
A l’origine les alias d’adresses emails avaient été créés par ispconfig que j’ai désinstallé depuis mais dont j’ai gardé les éléments de conf mysql.
lorsqu’un message vers un alias est reçu il donne l’erreur suivante dans syslog:
postfix/pipe[108016]: 52C094B00FAE: to=<test@mondomaine.com>, relay=dovecot, delay=0.23, delays=0.16/0.01/0/0.05, dsn=5.1.1, status=bounced (user unknown)
Pourtant lorsque j’interroge manuellement la base l’alias est bien reconnu et renvoit le bon email :
> postmap -q test@mondomaine.com mysql:/etc/postfix/mysql-virtual_forwardings.cf
tmp@mondomaine.com
Ce serveur fonctionnait correctement. J’ai entre temps upgradé de 9 à 11 et remplacé amavis et spamassassin par rspamd en suivant ce tuto.
