Add Domain specific DKIM in PMTA config

#MTAs

<virtual-mta ip1>

    smtp-source-host 192.198.0.1 host.domain.tld

    <domain *>

        max-msg-rate 400/h

    </domain>

</virtual-mta>

#DKIM Keys

domain-key key1,domain1.tld,/etc/pmta/keys/key1.domain.tld

domain-key key2,domain2.tld,/etc/pmta/keys/key2.domain.tld

domain-key key3,domain3.tld,/etc/pmta/keys/key3.domain.tld

#Specify the DKIM for specific Domain using Directive

<domain domain1.tld>

    dkim-sign yes

    smtp-hosts [127.0.0.1]:587

    dkim-identity @domain1.tld

</domain>

<domain domain2.tld>

    dkim-sign yes

    smtp-hosts [127.0.0.1]:587

    dkim-identity @domain2.tld

</domain>

<domain domain3.tld>

    dkim-sign yes

PowerMTA System requirements

It depends on how big your email lead list is. For example, if you want to send 10000/hour emails , the optimum server would have 10 IPs and would be using 10 domains or subdomains. This way each IP/domain would send emails1000/hour. The more IPs and domains the better variety can be applied as follows.

Minimum system requirements for sending from 1 IP/domain:

  • VPS (KVM, OpenVZ, XEN, …)
  • CentOS 6 x64 minimal
  • 1 core
  • 1 GB RAM
  • 10 GB HDD
  • 1 IP

I theory a server like this could also be used with more IPs and domains but could get to its peak point.
Here are recommended system requirements based on number of used IPs/domains
Local PowerMTA


Everything will run on the same server so our server must have enough power. Here are our recommendations:

5-19 IPs/domains

  • VPS or Dedicated server
  • 2 cores
  • 8 GB RAM
  • 20 GB SSD
20-99 IPs/domains

  • VPS or Dedicated server
  • 4 cores
  • 16GB RAM
  • 40 GB SSD
100+ IPs/domains

  • VPS or Dedicated server
  • 8 cores
  • 32GB RAM
  • 100 GB SSD
Here a saying we all know from Jeremy Clarkson would come in handy, POWER!!!! And more power we have the better.

External PowerMTA
In this case, Mumara will run on one more powerful server and PowerMTA will be installed on many cheaper servers. Here are our recommendations:

Main server – Mumara

  • 4 cores
  • 16GB RAM
  • 40 GB SSD
  • 1 IP

MTAs – PowerMTA
  • 1 core
  • 1 GB RAM
  • 10 GB HDD
  • 1 IP
This guideline covers both scenarios.
