Re : Postfix lent

Bon j'ai effectivement réussis a appliquer les réglages ! Malheureusement impossible de dire si cela à eu une influence sur la vitesse d'envoi puisque notre merveilleux fournisseur de VPS (LWS) nous a couper notre service SMTP parce qu'il soupçonne un spam... Donc je referais des test quand les choses seront revenues a la normale.

En tou cas merci de m'avoir répondu aussi vite :-)

Re : Postfix lent

Bon et bien la vitesse c'est un petit peu amélioré, on est passer de 40 mail/minute à 70 mail/minute. Ça me parait encore assez léger je trouve. Mais peut être ce débit est-il normal ? Les mails qui sont envoyer font environs 400 ko.

Regarde ici https://help.ubuntu.com/community/Postf … New#Amavis en bas de page il y a des trucs pour optimiser Amavis.

Merci pour ta réponse !
Malheureusement cela ne m'aide pas beaucoup, puisque j'ai désactiver amavis... Je présume que cela doit venir de ma configuration de postfix ou quelque chose du genre.

smtp_destination_concurrency_limit = 2

de visu, cela ralentit, bride le smtp, sur les connexions parallèles. Le surplus génère des erreurs de connexions, facilement déduites via fail2ban; exemple, la plupart des attaques smtp, a tendance à utiliser un nombre élevé de connexions parallèles.

sudo postconf -d | grep destination_concurrency_limit

sudo postconf -n | grep destination_concurrency_limit
default_destination_concurrency_limit = 5

sudo postconf -d | grep destination_rate_delay
default_destination_rate_delay = 0s
lmtp_destination_rate_delay = $default_destination_rate_delay
local_destination_rate_delay = $default_destination_rate_delay
