Mais du coup, dans ton main.cf, tu présentes ça comment ?  
juste avec la ligne

```nohighlight
transport_maps = hash:/etc/postfix/transport

```

sans rien d’autre ?

Bon, ceci dit, j’ai fait la même conf que toi et le résultat dans la log ne me parait pas logique. J’ai envoyé à la file 5 mails au même destinataire chez orange :

```

D’après moi, il y aurait dû y avoir au 3eme mail un délais de 10 sec pour envoyer le 4eme, alors que quand on regarde la valeur delay, ça a pris moins d’une seconde.

Ou alors j’ai mal compris le sens des variables **smtp\_destination\_concurrency\_limit** et **slow\_destination\_rate\_delay**
