Bonjour,
je viens vers vous car j’ai un problème concernant un envoi de mail via le service postfix/dovecot que j’ai installé sur mon vps OVH.
En effet, pour certaines adresses, les mails sont parfaitement transmis. Cependant, pour d’autres, je recois une notification de non délivrance avec l’erreur, le destinataire étant le culture-ion :
[quentin.jousset@culture-ion.fr]: host culture-ion.fr[46.105.171.70] said: 550-Verification failed for [ilt@gaminisen.fr] 550-The mail server could not deliver mail to [ilt@gaminisen.fr] . The account or domain may not exist, they may be blacklisted, or missing the proper dns entries. 550 Sender verify failed (in reply to RCPT TO command)
Je poste également ma configuration ici :
alias_database = hash:/etc/aliases

Merci beaucoup de votre aide !
