Powermta Configuration Guide Top Extra Quality

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 yourdomain.com> max-msg-rate 20/h # 20 emails per hour max-cold-virtual-mta-msg 100/day max-rcpt-rate 20/m # 20 recipients per minute </domain>

: Limits the maximum number of concurrent SMTP connections to a domain.

Every sending IP must have a reverse DNS record matching your sending domain. Contact your hosting provider to configure: powermta configuration guide top

<virtual-mta warmup-medium> smtp-source-host 192.168.1.10 max-smtp-out 10 max-msg-rate 200/h # ~4,800/day </virtual-mta>
