Properly configured DNS is non-negotiable for good deliverability. You must set up the following records for your sending domains and IPs before you start sending traffic:
<domain gmail.com> max-msg-rate 1000/h max-smtp-out 20 use-starttls yes dkim-sign yes # Gmail is more forgiving on retries but much stricter on reputation. retry-after 2m </domain> powermta configuration guide top
# /etc/pmta/config
Secure the HTTP management console inside your configuration: Queue Management # Global DKIM Configuration dkim-sign yes
# Main configuration file: /etc/pmta/config # Maximize concurrent connections globally max-msg-rate 0 # 0 means unlimited, controlled per domain max-smtp-out 1000 # Total maximum simultaneous outbound connections # Thread management delivery-threads 50 # Number of CPU threads dedicated to delivery Use code with caution. Queue Management powermta configuration guide top
# Global DKIM Configuration dkim-sign yes dkim-algorithm rsa-sha256 # Domain Specific Keys domain-key yourdeliverydomain.com, dkim1, /etc/pmta/keys/://yourdeliverydomain.com.pem Use code with caution.
