Possibly, but it is hard to say. Deliverability is a tough issue which is not entirely on topic here (usually it has much more to do with your IP reputation than with any Postfix settings.) If your relayhost IP has a worse reputation than you do, you're in bad luck. Look into DKIM signing, and possibly even SPF. Those are more likely to help with the problem you are seeing. > Are there a Way to tell my postfix "dont sent this external domain > "externaldomain1.com" through the relayhost, try to send it > directly, the rest external mails, keep using the relayhost" ?...
