Problème d’envoi de mail serveur postfix/dovecot/sasl

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
alias_maps = hash:/etc/aliases
append_dot_mydomain = no
biff = no
compatibility_level = 2
dovecot_destination_recipient_limit = 1

mydestination = localhost.ovh.net, localhost
myhostname = gaminisen.fr
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
myorigin = /etc/mailname

recipient_delimiter = +
relayhost =
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache
smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU)
smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, rej                                                                                                             ect_unauth_destination

Merci beaucoup de votre aide !
